PEG-400 assisted synthesis of 2-(R-benzylidene)-5-(R-cinnamylidene)cyclopentanones

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.…”
