Abstract

A new strategy to access processable oligophenylene segmented polymers through thermal cyclodimerization of aromatic trifluorovinyl ether monomers to perfluorocyclobutyl (PCFB) polymers was discussed. Ether oligophenylene monomers were polymerized via thermal cyclopolymerization, which afforded the first PFCB aryl ether polymers containing oligophenylene units in the main chain. It was observed that the trifluorovinyl ether-substituted oligophenylenes exhibit dramatically enhanced solubility, allowing characterization by ¹H NMR, ¹³C NMR, and solution spectroscopy. Terphenyl poly1 was found to exhibit a thermotropic nematic mesophase and was characterized by polarized optical microscopy and X-ray diffraction. It was found that PFCB cyclodimerization due to condensate free polymerization offers a simple thermal approach to liquid crystallographic (LC) structures.
