Paper Abstract

We report the synthesis, electronic absorption and molecular second order nonlinear optical properties of a novel series of donor-acceptor substituted conjugated compounds with five- membered heteroaromatic rings as conjugating units. Our experimental studies demonstrate that the replacement of benzenoid rings in 4-dimethylamino-4'-nitrostilbene (DANS) and 4- dialkylamino-4'-dicyanovinylstilbene (DADVS) compounds with thiophene moieties significantly enhances their charge-transfer properties and molecular second order nonlinear optical properties.
