New fluorescent markers with a large Stokes shift

摘要

The invention relates to fluorescent dyes (fluorophores) based on polymethines for use in optical, in particular fluorescence-optical determination and detection methods, for example in medicine, in pharmacy and in bio, material and environmental science. DOLLAR A task was to create polymethine-based fluorophores with a large Stokes shift, high photo and storage stability and high fluorescence quantum yield, which can be excited in the simplest possible way by white light sources or by laser radiation in the UV, visible or NIR spectral range. DOLLAR A According to the invention, dyes based on polymethines of the general formulas I, II and III DOLLAR F1 are used.
