摘要：

A series of high-temperature and chemically stable chromophores were covalently attached onto the polyquinoline backbones. These NLO side-chain polyquinolines possess high glass transition temperature (T-g > 200 degrees C), excellent processibility, thermal stability, and electrooptical properties. Poling results of these polymers demonstrate large electrooptic coefficient (r(33)) values (up to 17 pm/V measured at 0.83 mu m) and good temporal alignment stability of polymer films (the r(33) value retained more than 80% of the original value at 100 degrees C for more than 3000 hours).
