Abstract
Synthesis, characterization, and photophysical properties for a few optical chromophores are reported. Phenothiazine and carbazole units played an important role to contribute high electron donability and connect the resonance pathway via conjugate effect in the cyclized ring besides the aromatic ring. Theoretical calculations and an absorption spectroscopic study gave useful information about the energy states and structures of chromophores.
Dedicated to Professor Marian Mikołajczyk, CBMiM PAN in Łódź, Poland, on the occasion of his 70th birthday.
