PREPARATION AND PHOTOCONDUCTIVITY OF C-60 CHEMICALLY-MODIFIED POLY(N-VINYLCHLOROMETHYLCARBAZOLE)

C-60 chemically modified poly(N-vinyl-chloromethylcarbazole) was synth esized by the reaction of C-60 with living poly( N-vinyl-chloromethylc arbazole) (PVCC) carbanions, which were prepared by alpha-position pro ton abstraction with NaH. The structural characterization techniques u sed were ultraviolet-visible, Fourier transform-infrared spectroscopy, X-ray diffraction, scanning electron microscopy, nuclear magnetic res onance and electron spin resonance, etc. All experimental results prov ed that C-60 was covalently attached on the backbone chain of PVCC and consequently causes a remarkable enhancement of the photoconductivity of the parent polymer. Also, it was found that fullerenation of PVCC modified both the electronic structures of the carbazole pendant group and the interchain structure. (C) 1998 Chapman and Hall.
