The present disclosure is directed dye compounds containing a hydrazinyl substituent and optionally, one or more negatively charged groups, such as sulfonate, phosphate, phosphonate, and/or carboxylate groups and dye compounds containing an aminooxy substitutent. The compounds are useful in the detection of analytes containing aldehyde and ketone groups, including, for example, glycans.

Provided is a method for producing (alkyl)arene compounds represented by Formulae 3-1, 3-2, and 3-3 by the Friedel-Crafts alkylation reaction of alkyl halide compounds and arene compounds using organic phosphine compounds as a catalyst. ##STR00001##

The present invention relates to: an organic compound represented by a combination of Chemical Formulas 1 and 2; an organic optoelectronic device comprising the organic compound; and a display device.

##STR00001##

Provided are an arylamine compound and an organic light-emitting device including the same.

A compound of formula (I): ##STR00001## wherein p is at least 1, n is at least 1 and less than or equal to p; Ar is a polycyclic aromatic moiety, R.sup.1 is hydrogen or an optionally substituted hydrocarbyl group and each of R.sup.2, R.sup.3 and R.sup.4 is independently an optionally substituted hydrocarbyl group, provided that at least one of R.sup.2, R.sup.3 and R.sup.4 has at least 6 carbon atoms.

An aromatic amine derivative represented by the following formula (1):

##STR00001##

wherein at least one of R.sub.1 to R.sub.8 is a group other than a hydrogen atom, Ar.sub.1 to Ar.sub.4 are a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms.

The present invention relates to novel light-emitting materials. These materials comprise a non-aromatic spiro polycyclic group. This new side chain could reduce the stacking of the light-emitting materials and result in high PLQY.

Disclosed is a light-emitting material for organic electroluminescent (EL) devices which is composed of an asymmetric anthracene derivative of a specific structure. Also disclosed are a material for organic EL devices and an organic EL device wherein an organic thin film layer composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. At least one layer composed of the organic thin film layer contains the material for organic EL devices by itself or as a component of a mixture. Consequently, the organic EL device has a high efficiency and a long life. Also disclosed are a light-emitting material for organic EL devices and material for organic devices which enable to realize such an organic EL device.

Methods of forming arenes, including asymmetrical arenes, such as asymmetrical pyrene derivatives. Substituents of starting materials may be selected to direct a photochemical cascade and possibly a 1,2-aryl shift. The methods may include a Mallory cyclization, which is controlled, at least in part, by substituents of the starting materials. Compounds and compositions including asymmetrical arenes.

A process is provided, comprising reacting a (hetero)aryl 1,3-dipole compound with a (hetero)cycloalkyne, wherein the (hetero)aryl 1,3-dipole compound comprises a 1,3-dipole functional group bonded to a (hetero)aryl group, and wherein the (hetero)aryl 1,3-dipole compound is a (hetero)aryl azide or a (hetero)aryl diazo compound; wherein: (i) the (hetero)aryl group of the (hetero)aryl 1,3-dipole compound comprises a substituent (ii) the (hetero)aryl group of the (hetero)aryl 1,3-dipole compound is an electron-poor (hetero)aryl group
and wherein the (hetero)cycloalkyne is a (hetero)cyclooctyne or a (hetero)cyclononyne according to Formula (1). The invention also relates to the products obtainable by the process according to the invention.
