Three novel "Y"-shaped acceptor-π-donor-π-acceptor-type compounds were synthesized from 4,4′-(hexylimino)bis(benzaldehyde) as a donor and 2-methylthiazolo[4,5-b]quinoxaline derivatives as strong electron acceptors condensed by classical Knoevenagel condensation. Their absorption, emission, and thermal properties and electrochemical stability were investigated. It was found that the strong electron acceptor-donor chromophoric system of these compounds showed high Stokes shift, excellent thermal stability, and electrochemical reversibility. The solvatochromic behavior of these colorants was studied by using various solvents such as toluene, chloroform, ethyl acetate, tetrahydrofuran, methanol, and N,N-dimethylformamide in increasing order of polarity. The dyes were characterized by means of elemental analysis, 1H NMR, and mass spectrometry. Springer-Verlag 2010.
