OPTICAL-PROPERTIES OF PERFLUOROALKYLATED POLY(DIPHENYLACETYLENE)

Optical properties of a soluble conducting polymer, perfluoroalkylated poly(diphenylacetylene) (PFPDPA) were clarified. The band-gap energy was evaluated to be about 2.7 eV. Relatively strong fluorescence was o bserved in PFPDPA, while poly(diphenylacetylene) (PDPA) is considered to be a conducting polymer with a degenerated ground state in which a soliton is considered to play an important role. A light-emitting diod e (LED) with In-Mg/PFPDPA/indium-tin-oxide (ITO) configuration was fab ricated and green light emission was observed.
