Abstract
AbstractA detailed photophysical behavioral study of zinc (II) complexes of Schiff bases 2,6‐bis((E)‐((2‐(dimethylamino) ethyl)imino)methyl)‐4‐R‐phenol, where R = methyl (1)/isopropyl (2)/tertiary butyl (3)/chloro (4) for ligands 1 to 4 (HL1 to HL4) have been done by utilising the surfactant cetyltrimethyl ammonium bromide as the biomimicking environment. Steady state absorption and emission studies have been studied to investigate the course of deciphering of the photophysical behavior of the complexes. The study reveals modification of the photophysical properties of the complexes based on the effect of polarity of the micellar environment. The studies reported in the present investigation describe the initial reduction of fluorescent intensity of all the four complexes followed by an escalation in intensity. The binding constant values reveal that the Schiff bases bind to the micellar compartment. The course of binding is however found to be dependent on the functional group of the ligand which is studied and reported in the present context.
