Abstract
Abstract Three novel chromophores, trans -dimethyl 4-(4′-methoxystyryl)pyridine-2,6-dicarboxylate ( 5 ), trans -dimethyl 4-(4′-nitrostyryl)pyridine-2,6-dicarboxylate ( 6 ), trans -dimethyl 4-(2-(1H-benzo[d]imidazol-2-yl)vinyl)pyridine-2,6-dicarboxylate ( 7 ) were synthesized and characterized. Their absorption, photoluminescence as well as two-photon absorption properties were studied. These compounds have strong linear absorption bands around 322–340 nm. From femtoscond nonlinear transmission measurements, compounds 5 and 7 have effective two-photon cross sections ( σ ) at 800 nm.
