摘　　要：本文合成了八种光致变色二芳烯化合物,研究了它们的光致变色性质,并综述了它们在光子型光信息存储技术中的应用。在光辐照下,这些化合物在溶液和PMMA膜中均具有良好的光致变色特性。使用这些化合物作为光存储介质,成功进行了系列高密度光子型光信息存储实验,包括全息光存储、双光子光存储和多波长光存储。结果表明:二芳烯材料是光子型全息、双光子和多波长光存储技术中可采用的最理想的存储介质之一。Eight diarylethene compounds were synthesized and their photochromic properties were investigated. These compounds showed good photochromic reactions both in solution and in PMMA amorphous film by photo-irradiation. Using them as a recording media, a series of high-density photon-mode optical recording tests, including holographic optical recording, two-photon 3D optical recording and multi-wavelength optical recording, were performed successfully on the sample discs. The results indicate that diarylethene materials are the most promising candidates for all types of photon-mode optical recording described above.
