Synthesis and characterization of new push-pull anthraquinones bearing an arylthienyl-imidazo conjugation pathway as efficient nonlinear optical chromophores

Compounds 1 were synthesized, in good to excellent yields (72-87%), through condensation of formyl-arylthiophene precursors 2 with 1,2-diaminoanthraquinone in ethanol at reflux, followed by cyclisation of the imine intermediate with Pb(OAc)4 in acetic acid at room temperature. Evaluation of the ther...
