Abstract

A single photorefractive (PR) molecule was designed and synthesized by incorporating an oligo(3-alkylthiophene) segment with a nonlinear optical chromophore. The conjugated oligothiophene moiety played as both the photocharge generator and the charge transporter. The PR properties of this molecule showed a strong dependence on the applied electric field due to the orientational enhancement effect, as well as the linear electro-optic effect. Large net gain coefficient and diffraction efficiency were achieved in this single molecule system. The studies of the dynamics of the formation of the holographic gratings revealed that this material has a fast response time to optical signals.
