Synthesis of sulfone-substituted thiophene chromophores for second-order nonlinear optics

Abstract

A new series of conjugated thiophene compounds 1-4 containing methylsulfonyl and phenylsulfonyl accepters have been synthesized which possess efficient second-order optical nonlinearities, high thermal stability and good transparency for use as nonlinear optical materials.
