Author Affiliations +
Optical properties and electronic energy structures of di- substituted acetylene polymers have been studied. Strong blue and green photoluminescence and electroluminescence have been observed in the poly(diphenylacetylene) derivatives and poly(1-alkyl-2-phenylacetylene) derivatives, contrary to trans-polyacetylene, in which only very weak photoluminescence are observed at infrared region. The dependence of optical properties of the di-substituted polyacetylene derivatives such as photoluminescence intensity and electroluminescence efficiency on the molecular structure of substituents and the change of optical properties upon electrochemical doping and their interpretation by soliton model have also bee discussed. Spectral narrowing in photoluminescence of some di- substituted polyacetylenes have also been studied.
