The present invention relates to the use of aromatic boronic acid or borinic acid derivatives in organic electronic devices, in particular electroluminescent devices.

Organic dye for a dye sensitized solar cell (DSSC) comprising at least one substituted pyrrole group. Said organic dye is particularly useful in a dye sensitized photoelectric transformation element which, in its turn, can be used in a dye sensitized solar cell (DSSC).

Sulfonated 2(7)-aminoacridone and 1-aminopyrene dyes and their use as fluorescent tags, in particular for carbohydrate analysis The invention relates to fluorescent dyes with multiple negatively charged groups in their ionized form which are aminoacridone sulfonamides or 1-aminopyrenes having of one of the following general formulae A-D: Formula (A), Formula (B), Formula (C), Formula (D), wherein the ionizable groups X are typically selected from the following: SH, COOH, SO.sub.3H, OSO.sub.3H, OP(O)(OH).sub.2, OP(O)(OH)R.sup.a, P(O)(OH).sub.2, P(O)(OH)R.sup.a, where R.sup.aC.sub.1-C.sub.4alkyl or substituted C.sub.1-C.sub.4alkyl. The invention further relates to the use of these dyes as fluorescent tags, in particular for reducing sugars and glycans. ##STR00001##

A composition includes a functionalized fluorescent dye. The functionalized fluorescent dye includes an isothiocyanate-containing compound functionalized with a functional group. The functional group includes a primary amine. The functionalized fluorescent dye can be mixed with a fluid to form a tracer fluid for tracing fluid flow in a subterranean formation.

The invention relates to novel fluorescent dyes based on the following pyrenyloxy sulfonamide structure: ##STR00001##
wherein R.sup.1 is a leash joined to the pyrenyloxy group via an ether link containing generally a reactive functional group such as, activated carbonate, activated ester, amino group, azide or alkyne for conjugation with biomolecules; R.sup.2 and R.sup.3 are hydrogen atoms, or short alkyl chains, or cyclic rings with or without heteroatoms such as nitrogen, oxygen, sulfur, phosphorus. The spectral properties of the fluorescent dyes are sufficiently different in wave-lengths and intensity from fluorescein as to permit simultaneous use of fluorescein and/or more other fluorescent dyes with minimum interference and to avoid interference from endogenous green fluorescent protein in biological system. The dyes are non-ionic to facilitate their entry into cells for intracellular detection. The non-ionic structure also precludes undesired electrostatic reactions with ionic sites on biological components and structures. The dyes have bigger Stokes' shifts than other dyes with similar spectral properties allowing use of simpler, more efficient detection equipment, are not sensitive to pH, and have good solubility in aqueous solution.
