Synthesis of hydroboration copolymer of TCNQ and formation of polymer charge transfer complex therefrom

Summary Novel TCNQ copolymers were prepared by hydroboration copolymerization of TCNQ with mesitylborane. The polymers obtained exhibited characteristics as a new class of polymer electron acceptors. When these polymers were treated with p-phenylenediamine at 80°C – 140°C in diglyme solutions, charge transfer complex formation was observed in UV-vis spectra. Hydroboration polymerization of p-, m-dicyanotetrafluorobenzene also proceeded to give the corresponding polymer electron acceptors.
