The first polysilyne having a perfluorinated aryl group, poly(pentafluorophenylsilyne), was prepared through a combination of the Grignard reaction of bromopentafluorobenzene and tetrachlorosilane and the subsequent electrochemical polymerization using a magnesium electrode. The absorption and emission spectra of the polymer showed the characteristic of polysilyne which has a silicon network structure. The emission decay of poly (pentafluorophenylsilyne) measured by the time-resolved single photon counting technique showed non-single exponential kinetics. These optical properties were compared with those of poly(phenylsilyne).
