DESCRIPTION OF EMBODIMENTS
Definitions
[0053] Throughout this specification the word comprise, or variations such as comprises or comprising, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.
[0054] Throughout this specification, the term consisting essentially of is intended to exclude elements which would materially affect the properties of the claimed composition.
[0055] Throughout the present specification, various aspects and components of the disclosure can be presented in a range format. The range format is included for convenience and should not be interpreted as an inflexible limitation on the scope of the disclosure. Accordingly, the description of a range should be considered to have specifically disclosed all the possible sub-ranges as well as individual numerical values within that range, unless specifically indicated. For example, description of a range such as from 1 to 5 should be considered to have specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 5, from 3 to 5 etc., as well as individual and partial numbers within the recited range, for example, 1, 2, 3, 4, 5, 5.5 and 6, unless where integers are required or implicit from context. This applies regardless of the breadth of the disclosed range. Where specific values are required, these will be indicated in the specification.
[0056] Herein the term about encompasses a 10% tolerance in any value(s) connected to the term.
[0057] In the present specification, the structural formula of a compound may represent a certain isomer for convenience in some cases, but the present disclosure, unless otherwise indicated, includes all isomers, such as geometrical isomers, for example syn- and anti-isomers, optical isomers based on an asymmetrical carbon, stereoisomers, tautomers, and the like. In addition, a crystal polymorphism may be present for the compounds represented by the formula. It is noted that any crystal form, crystal form mixture, or anhydride or hydrate thereof is included in the scope of the present disclosure.
[0058] Isomerism means compounds that have identical molecular formulae but differ in the sequence of bonding of their atoms or in the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed stereoisomers. Stereoisomers that are not mirror images of one another are termed diastereoisomers, and stereoisomers that are non-superimposable mirror images of each other are termed enantiomers or sometimes optical isomers. A mixture containing equal amounts of individual enantiomeric forms of opposite chirality is termed a racemic mixture.
[0059] A carbon atom bonded to four non-identical substituents is termed a chiral centre.
[0060] Chiral isomer means a compound with at least one chiral centre. Compounds with more than one chiral centre may exist either as an individual diastereomer or as a mixture of diastereomers, termed diastereomeric mixture. When one chiral centre is present, a stereoisomer may be characterized by the absolute configuration (R or S) of that chiral centre. Absolute configuration refers to the arrangement in space of the substituents attached to the chiral centre.
[0061] Geometric isomer means the diastereomers that owe their existence to hindered rotation about double bonds. These configurations are differentiated in their names by the prefixes cis and trans, or Z and E, which indicate that the groups are on the same or opposite side of the double bond in the molecule
[0062] Furthermore, the structures and other compounds discussed in this disclosure include all atropic isomers thereof. Atropic isomers are a type of stereoisomer in which the atoms of two isomers are arranged differently in space. Atropic isomers owe their existence to a restricted rotation caused by hindrance of rotation of large groups about a central bond.
[0063] Herein the compounds of Formula (I) may exist in either the syn or the anti form. For example:
##STR00010##
are anti and syn isomers of the same compound, respectively.
[0064] Tautomer is one of two or more structural isomers that exist in equilibrium and is readily converted from one isomeric form to another. This conversion results in the formal migration of a hydrogen atom accompanied by a switch of adjacent conjugated double bonds. Tautomers exist as a mixture of a tautomeric set in solution. In solid form, usually one tautomer predominates. In solutions where tautomerisation is possible, a chemical equilibrium of the tautomers will be reached. The exact ratio of the tautomers depends on several factors, including temperature, solvent and pH. The concept of tautomers that are inter-convertible by tautomerisations is called tautomerism.
[0065] Alkyl means a straight chain or branched, noncyclic or cyclic, saturated aliphatic hydrocarbon. The alkyl group may contain from 1 to 24 carbon atoms. Representative saturated straight chain alkyls include methyl, ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, and the like; while saturated branched alkyls include isopropyl, sec-butyl, isobutyl, tert-butyl, isopentyl, and the like. Representative saturated cyclic alkyls include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and the like; while unsaturated cyclic alkyls include cyclopentenyl and cyclohexenyl, and the like.
[0066] Alkenyl means an alkyl, as defined above, containing at least one double bond between adjacent carbon atoms. The alkenyl group may contain from 2 to 24 carbon atoms. Alkenyls include both cis and trans isomers. Representative straight chain and branched alkenyls include ethylenyl, propylenyl, 1-butenyl, 2-butenyl, isobutylenyl, 1-pentenyl, 2-pentenyl, 3-methyl-I-butenyl, 2-methyl-2-butenyl, 2,3-dimethyl-2-butenyl, and the like.
[0067] Alkynyl means any alkyl or alkenyl, as defined above, which additionally contains at least one triple bond between adjacent carbons. The alkynyl group may contain from 2 to 24 carbon atoms. Representative straight chain and branched alkynyls include acetylenyl, propynyl, 1-butynyl, 2-butynyl, 1-pentynyl, 2-pentynyl, 3-methyl-1-butynyl, and the like.
[0068] The term aryl disclosed herein refers to a mono- or polycyclic aromatic hydrocarbon systems. The aryl systems may have having 3 to 22 carbon atoms, which can be optionally substituted. The term aryl also includes systems in which the aromatic cycle is part of a bi- or polycyclic saturated, partially unsaturated and/or aromatic system, such as where the aromatic cycle is fused to an aryl, cycloalkyl, heteroaryl or heterocyclyl group as defined herein via any desired and possible ring member of the aryl radical. The bonding to the compounds of the Formula (1) can be affected via any possible ring member of the aryl radical. Examples of suitable aryl radicals are phenyl, biphenyl, naphthyl, 1-naphthyl, 2-naphthyl and anthracenyl, but likewise indanyl, indenyl or 1,2,3,4-tetrahydronaphthyl.
[0069] The term unsubstituted means that the corresponding radical, group or moiety has no substituents.
[0070] The terms optionally substituted, comprises one or more substituents or substituted means that a corresponding radical, atom, group or moiety on a compound may have one or more substituents present. Where a plurality of substituents, or a selection of various substituents is specified, the substituents are selected independently of one another and do not need to be identical. In some case, at least one hydrogen atom on the radical, group or moiety is replaced with a substituent. In the case of an oxo substituent (O) two hydrogen atoms may be replaced. In this regard, substituents may include: alkyl, alkene, alkyne, halogen, nitro, cyano, hydroxy, sulfonic, thiol, ether, amino, alkylamino, dialkylamino, haloalkyl, hydroxyalkyl, alkoxy, haloalkoxy, aryloxy, heteroaryloxy, aralkyloxy, alkylthio, carboxamido, sulfonamido, alkylcarbonyl, arylcarbonyl, alkylsulfonyl, arylsulfonyl, carboxy, carboxyalkyl, alkyl, cycloalkyl, alkenyl, alkynyl, aryl, heteroaryl, heterocyclo, alkoxyalkyl, (amino)alkyl, hydroxyalkylamino, (alkylamino)alkyl, (dialkylamino)alkyl, (cyano)alkyl, (carboxamido)alkyl, mercaptoalkyl, (heterocyclo)alkyl, (cycloalkylamino)alkyl, (C.sub.1-C.sub.4 haloalkoxy)alkyl, (heteroaryl)alkyl, or perylene, oxo, heterocycle, OR.sup.x, NR.sup.xR.sup.y, NR.sup.xC(O)R.sup.yNR.sup.xSO.sub.2R.sup.y, C(O)R.sup.x, C(O)OR.sup.x, C(O)NR.sup.xR.sup.y, SO.sub.qR.sup.x and SO.sub.qNR.sup.xR.sup.y, wherein q is 0, 1 or 2, R.sup.x and R.sup.y are the same or different and independently selected from hydrogen, alkyl or heterocycle, and each of said alkyl and heterocycle substituents may be further substituted with one or more of oxo, halogen, OH, CN, alkyl, OR, heterocycle, NR.sup.xR.sup.y, NR.sup.xC(O)R.sup.yNR.sup.xSO.sub.2R.sup.y, C(O)R.sup.x, C(O)OR.sup.x, C(O)NR.sup.xR.sup.y, SOR.sup.x and SONR.sup.xR.sup.Y.

[0293] A mixture of 1,7 & 1,6 dibromoperylene-3,4:9,10-tetracarboxylic acid bisanhydride (Scheme 1), was generated by bromination of perylene 3,4:9,10 tetracarboxylic bis anhydride according to a literature procedure (J. Org. Chem. 2004, 69, 7933-7939).
[0294] A mixture of 100 g of perylene-3,4:9,10-tetracarboxylic acid bisanhydride (Compound 1) and 1.5 kg of 100 wt % sulfuric acid was stirred for 12 hours at room temperature, and subsequently I.sub.2 (2.5 g) was added. The reaction mixture was heated to 85 C., and 90 g of bromine was added dropwise over a time period of 8 hours down a large, water-cooled condenser. After bromine addition, the reaction mixture was heated for an additional 10 hours at 85 C. HBr gas formed during the reaction was vented from the top of the condenser by a gentle stream of N.sub.2 gas into a 500 mL aqueous quenching solution of w/w 5% NaOH, 0.05% Na.sub.2S.sub.2O.sub.5. The reaction was cooled to room temperature and excess bromine was removed by bubbling the reaction with N.sub.2 gas into the quenching solution. 65 mL of water was added carefully to precipitate the product. The resulting precipitate was separated by filtration through a G4 funnel, washed with 3300 g of 86% sulfuric acid followed by a large amount of water. The product was dried in a vacuum to give 135 g (96%) of an isomeric mixture of 1,7 & 1,6 dibromoperylene-3,4:9,10-tetracarboxylic acid bisanhydride as a red powder. The crude product could not be purified since it is insoluble in organic solvents and was used without further purification.

[0295] The literature has shown that the trans and cis isomers, typically in an 8:2 ratio, along with trace amounts of 1,6,7 tribromoperylene-3,4:9,10-tetracarboxylic acid bisanhydride (>2%) are formed in this procedure. These isomers generally persist in the same ratios in the dyes derived from them described herein.
3,4:9,10-Bis(1,2-benzimidazole)-1,7 & 1,6 Dibromoperylene
[0296] 3,4:9,10-bis(1,2-benzimidazole)-1,7 & 1,6 dibromoperylene (Compound 2) was formed by taking 40 g of Compound 1 (36 mmol) and 16 grams of Zn(OAc).sub.2.H.sub.2O were dispersed in 350 mL of a stirring 1:1 v/v mixture of n-butanol and propionic acid. 10 g of o-phenylene diamine was added and the reaction was brought to reflux under N.sub.2. The reaction continued for 6 hours and was then allowed to cool to room temperature. The resulting slurry was filtered directly, then washed with 300 mL of a 9:1 MeOH:water (v/v) mixture. The solid cake was then washed with multiple portions of hot water, followed by 1% 2M HCl in acetone washings (3200 mL) that extracted light brown fractions of excess o-phenylene diamine. Finally, two more washings with MeOH:water mixture followed by drying under vacuum afforded 43 g of a dark purple powder, with a yield of 86%. MS (MALDI) calc. for C.sub.36Br.sub.2H.sub.14N.sub.4O.sub.2 694.33, found 694.27 UV/vis in CHCl.sub.3, nm (log 10): 598 (5.68), 558 nm (5.61), 378 nm (5.13), Fluorescence max in CHCl.sub.3: 646 nm.
[0297] Scheme 2 shows the trans isomer. Trans and cis dibromo species are formed along with the possible anti and syn isomers for the benzimidazole groups. In total there are four possible isomers, as well as trace amounts of the tribromo species.
