碩士 === 國立中央大學 === 化學研究所 === 100 === In this thesis we have synthesized two series of chromophore with extended π-conjugation and another series are also been studied and discussed. We use UV/Visible absorption spectrometer and fluorescence spectrometer to study linear optical properties; use Nd:Yag Laser and Ti:Sapphire to probe nonlinear optical properties. In first series we use nitrogen atoms as π- bridge to extend conjugation to see whether if it’s a good π- bridge. In second series, four electron donor branches are fixed, only one electron acceptor branch is modified, thus we can inspect whether if it will does many differences on chromophores. The third series, with different number or orientation electron donors on carbon-carbon double bond, we can further study and realize molecular design in order to enhance 2PA.
