New methacrylate monomers with carbazole moieties as pendant groups were synthesized by multistep syntheses starting from carbazoles with biphenyl substituents in the aromatic ring. The corresponding polymers were prepared using a free-radical polymerization. The novel polymers contain N-alkylated carbazoles mono- or bi-substituted with biphenyl groups in the aromatic ring. N-alkyl chains in polymers vary by length and structure. All new polymers were synthesized to evaluate the structural changes in terms of their effect on the energy profile, thermal, dielectric, and photophysical properties when compared to the parent polymer poly(2-(9H-carbazol-9-yl)ethyl methacrylate). According to the obtained results, these compounds may be well suited for memory resistor devices. (c) 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2019, 57, 70-76
