DuBois was successfully able to polymerize the 11-(N- carbazolyl)undecylmethacrylate monomer (shown below). Dimethylformamide, instead of toluene, was used as the polymerization solvent, which increased the solubility of both the monomer and the polymer. Copolymers of 11-(N-carbazolyl)undecylmethacrylate were synthesized and investigated for holographic electro-optical applications.236

Prasad, et al., produced copolymers containing poly(2-N- carbazolylethylmethacrylate),237 where the poly(2-N-carbazolylethylmethacrylate) portion performed well as hole transporting agents for holography.238,239 As a hole transporting agent, isotactic poly(2-N-carbazolylacrylate) has demonstrated very high hole transporting mobilities.240,241 LeBarny also successfully synthesized a family of carbazole based methacrylates for promising holographic applications.242 Urya and Yozo used carbazole-phenoxy based methacrylates and acrylates to produce copolymers that were used as photoconductive materials capable of inducing a smectic phase in liquid
