Synthesis and evaluation of high-birefringence polymethacrylate having a diphenyl-diacetylene LC moiety in the side chain†
Abstract
We synthesized polymethacrylate with a diphenyl-diacetylene moiety in the side chain. It formed a nematic LC, which appears in the wide temperature region and vitrified at room temperature. The polymer exhibited a high-birefringence of ∼0.3 at 550 nm at room temperature.
