Synthesis and photophysical properties of a new type of merocyanine dye based on N-methyl derivatives of 4-aryl-2-(1-hydroxy-4-nitronaphthalen-2-yl)cyclopenta[b]pyridine

New type of cross-conjugated cyclopentanones as of ketocyanine dye - 2-arylidene-5-((dimethylamino)methylene)cyclopentanones: synthesis and photophysical properties

“…This work is a continuation of research on the synthesis and study of the photophysical properties of systems based on cyclopentanone [21][22][23][24] and is aimed at the synthesis of a series of new ketocyanines of the 2-arylidene-5-((dimethylamino)methylene)cyclopentanones and the study of their photophysical properties depending on the nature substituents and the polarity of the medium.…”
