  Push-Pull Chromophore with Phenylene and Thiophene as Conjugation Bridge for Electro-Optic Applications

  摘要：

  We designed and synthesized a push-pull type chromophore (PT-TCF) containing phenylene and thiophene ring as a conjugation bridge. Bulky alkyl chain was substituted into the phenylene bridge to minimize the intermolecular interaction among the neighbor molecules and to enhance solubility of the chromophore in solvents and a polymer host. H-1 NMR and (H-1H)-H-1 COSY spectroscopy confirmed that the chromophore was in all trans-ethenyl conformation. The chromophore exhibited fairly high melting point of 188 degrees C. The chromophore was thermally stable up to 220 degrees C in the nitrogen atmosphere. The relatively high melting point and decomposition on-set may be attributable to the rigid bridge component. The chromophore was blended with an optically transparent polymer host to make a thin film and then its macroscopic optical nonlinearities were evaluated. In a preliminary result, the polymer films containing PT-TCF as a concentration of 50 wt% exhibited electro-optic coefficient as large as 22pm/V taken at 1.55 mu m.
