Effects of chromophore interaction in the spectroscopy of ketocyanine dyes with a central pyranone or pyridone fragment
The study is devoted to investigation of a number of ketocyanine dyes (polyenic ω,ω′-bisaminoketones) with a central pyranone or pyridone fragment and respective polymethine salts by UV-VIS absorption and NMR spectroscopies. It was found that replacement of bridging O atom with NMe group suppresses...
