Abstract:
A series of 11 symmetric push-pull chromophores consisting of electron-accepting groups connected through a central pi-conjugated system derived from oligo(p-phenylene vinylene) (OPV) were designed and synthesized. Electronic and spectroscopic properties were investigated by UV-visible absorption, fluorescence spectroscopy, and cyclic voltammetry. By finely tuning the electron-withdrawing ability of the acceptors as well as the length of the pi-conjugated spacer, a wide range of dyes exhibiting strong absorption and emission were obtained.
