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 Rto Rare the same or different and signify in particular hydrogen or various organic residues, without or with functional groups, and Rincorporates 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.
