Abstract: Five imine derivatives were subsequently synthesized by condensation of 4,4'-sulfonyldianiline with substituted aromatic aldehyde or ketone in the presence of p-TsOH/EtOH. They are namely 4,4'-sulfonylbis(N-(2,4-dinitrobenzylidene)aniline) (C1), 4,4'-(4,4'-sulfonylbis(4,1-phenylene)bis(azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)dibenzaldehyde (C2), 4,4'-sulfonylbis(N-(1-(pyridin-2-yl)ethylidene)aniline) (C3), 4,4'-sulfonylbis(N-(1-(thiophen-2-yl)ethylidene)aniline) (C4), and 4,4'-sulfonylbis(N-(1-(furan-2-yl)ethylidene)aniline) (C5), with very good yields. The structure of the synthesized imine derivatives C1-C5 was investigated by various spectroscopic techniques (FTIR, 1H NMR, and mass spectroscopy). The photophysical properties of the synthesized derivatives C1-C5 were examined using fluorescence and UV-Vis spectroscopy. These compounds exhibit distinct emission and absorption profiles governed by their electronic structures, conjugation, and molecular reorganization.
