| 제목 | Synthesis and Optical Properties of Photorefractive Materials Containing Double-Functional Chromophore |
| 초록 | Photorefractive (PR) materials have attracted much attention as principal candidates for the medium of the optical memory system and real time holographic display. We have synthesized new PR active materials composed of the nonconjugated double functional moieties in a molecule. The double functional moieties contain a carbazole group for the hole-transporting and sulfonyl containing stilbene group for the second-order nonlinear optical (NLO) active chromophore. In this work, we describe PR effect of the double functional chromophore by using thick film in the presence of the photocharge generation sensitizer. The photorefractive properties were characterized by photocontivity, two-beam coupling(2BC) and degenerated four wave mixing (DFWM) technique to evaluate the double functional chromophore on the diffraction efficiency. |
