| Abstract: | A series of phenylenevinylene dimers with different electron releasing substituents were synthesized by Wittig reaction. Their electronic structures were characterized with cyclic voltammetry and UV Vis spectra, their energy levels were calculated with a quantum chemical calculation approach (AM1), the relationship between the photoluminescent property and the electronic structure was systematically discussed. |
