And by UV-visible absorption spectroscopy, fluorescence spectroscopy and other means, polymer were characterized.With solubility experiment, we obtained the following significant results: The functional poly(phenylacetylene) (that is, contains TPA) emit blue and green light under UV radiation , Its monomers and polymers have a clear distinction in the infrared bands 3200 nm. In 1 H NMR spectrum of the nuclear , double bonds and Three bonds have great different peak. Keywords: TPA,Poly(phenylacetylene),Irradiancy 目 录 中文摘要 I
