Abstract

An optically active, hyperbranched poly(fluorenevinylene) derivative was synthesized by polymerization of (−)-2,4,7-tris(bromomethyl)-9-neomenthyl-9-pentylfluorene. A spin-coated film sample of the polymer exhibited efficient circularly polarized light (CPL) emission in the visible range of 400–700 nm on photo excitation even without annealing processes leading to chain ordering.
