Abstract: Compounds, compositions, and methods for optical, including fluorescence optical, determinations useful in labelling biomolecules such as protein and deoxyribonucleic acid for their detection and quantitation. The compounds are diasteromeric cyanines with high hydrophilicity and other desirable properties.

Abstract: The invention relates to fluorescent dyes (fluorophores) based on polymethines for use in optical measurement and detection procedures, in particular those employing fluorescence, for example in medicine, in pharmacology and in the biological, materials and environmental sciences. The objective was to create fluorophores based on polymethines that have a large Stokes shift, high photostability, long storage life and a high fluorescent quantum yield, and that can be excited in the simplest possible manner by white-light sources or laser radiation in the UV, visible or NIR spectral region. According to the invention dyes on the basis of polymethines having the general formulas I, II or III are employed.

Abstract: The invention relates to compounds based on merocyanines with the general formulas I and/or II, where n=0 or an integer from 1 to 3, X=O or S and the residues R1 to R12 are the same or different and signify in particular hydrogen or various organic residues, without or with functional groups, and R2 incorporates an amine function. The compounds in accordance with the invention are suitable as fluorescent dyes (fluorophores) for used in optical determination and demonstration methods, in particular those employing fluorescence, for example in medicine, pharmacology and the biological, materials and environmental sciences. They are characterized by high photostability and long storage life, and exhibit a high fluorescence quantum yield. Excitation causing them to emit light can be achieved in a simple manner, by white-light sources or by laser irradiation in the UV, visible or NIR spectral region.
