摘要

Abstract: The synthesis and first hyperpolarizabilities ($beta@) of various donor-acceptor substituted thiophene containing compounds with extended conjugation are reported. Molecules incorporating the acceptor group, 3-phenyl-5-isoxazolone, that can gain aromaticity upon charge-separation had larger $beta than analogous molecules containing a dicyanovinyl acceptor. For both acceptors insertion of a vinyl group between the thiophene bridge and methine carbon of the acceptor enhances the second-order hyperpolarizability but does not lead to a significant decrease in thermal stability. The molecules have been incorporated into poly(methyl methacrylate) and the electro-optic coefficients of these host-guest polymers measured. !18
