摘要：
Highly thermal and photostable nonlinear optical polymers were obtained by covalently incorporating the tricyanovinylidenediphenylaminobenzene (TCVDPA) chromophore to a polycarbonate backbone. NLO polycarbonates with different chromophore attachment modes and flexibilities were synthesized. In spite of the high loading levels (ranging from 33.1 to 39.8 wt%), the polymers exhibit T(g)s as high as 215 degrees C, representing a significant improvement of over 100 degrees C of the material T(g) compared with that of the guest-host system containing the same chromophore at similar high loadings. EO coefficients up to 33 pm V(-1) at 830 nm were achieved, and a good temporal stability of the dipole alignment at 50 degrees C was observed.
