Two series of novel electro-optic (EO) polycarbonates containing two different kinds of nonlinear optical (NLO) chromophores with tricyanofurane (TCF) electron acceptor have been successfully prepared through the facile polycondensation between diol NLO chromophore and bisphenol A bis(chloroformate). These new polycarbonates which were characterized by 1H-NMR and Fourier transform infrared exhibited good solubility in common polar organic solvents. They also showed glass transition temperatures (Tg) in the range of 124-156 degrees C. The morphology studies indicated that these polycarbonates had good film quality before and after corona poling. The EO coefficients (r33) of two polycarbonates films were up to 45 pm/V (PC-TCFC-2) and 75 pm/V (PC-DFTC-3) at the wavelength of 1310 nm. Moreover, good temporal stability of the poling-induced dipole alignment was also achieved, and the resulting poled films of PC-TCFC-2 and PC-DFTC-3 could retain 90 and 80% of the initial EO activities at 85 degrees C for more than 500 h, respectively. Both EO activity and temporal stability results were better than the guest-host EO polymers containing the same concentration chromophores, which indicated that such kind of polycarbonates could effectively suppress the intermolecular electrostatic interaction and translate microscopic molecular hyperpolarizability into macroscopic EO activity.
