A new carbazole-functionalized norbornene derivative, 5-[methylbis(N-carbazolyl)silyl]-2-norbornene, was polymerized via living ring-opening metathesis polymerization (ROMP) with RuCl2-(=CHPh)(PCy3)(2). The resulting polymer was of high molecular weight and had a reasonably narrow molecular weight distribution (M-n = 57 000, M-w/M-n = 1.26). Block copolymers of the carbazole-functionalized monomer and a TMS-protected alcohol-functionalized norbornene derivative were also prepared using ROMP techniques. Microphase separation and selective reaction of the alcohol-functionalized domains with CdMe2 were observed by TEM. The UV-visible absorption spectra and fluorescence emission spectra of the polymers were similar to those of poly(N-vinylcarbazole).
