Abstract:A versatile, generally applicable synthetic methodology for side-chain NLO polycarbonates was developed. This represents the first example of covalent incorporation of NLO chromophores to a prepolymerized polycarbonate backbone. This methodology allows to adjust the polymer backbone structure and to vary the chromophore loading level in order to fine-tune the physical properties of the resulting material. The resulting NLO polycarbonates possess a high thermal stability, good solubility and can be easily processed into films of excellent quality. In spite of the high chromophore concentrations, fairly high glass transition temperatures were obtained (Tgs as high as 202 °C). Moreover, when a FTC type of chromophore was incorporated EO coefficients as high as 38 pm/V (at 1300 nm) were achieved. The combination of these properties provides a great promise for the development of EO devices based on NLO polymers.
