中文摘要:
      目的 设计并合成以苯并噻吩为烯桥,以萘和苯基噻唑为侧链的不对称二芳基乙烯类光致变色化合物,通过光化学性质研究阐明其应用前景。方法 通过经典的有机合成方法完成目标光致变色化合物的合成,进而通过薄层色谱分析法和柱层析法对目标化合物进行分离提纯,通过核磁共振氢谱(1H NMR)对目标化合物进行结构表征。最后,利用紫外可见分光光度计对目标化合物进行光化学性质测试,进而阐明其应用前景。结果 制备了两个含有萘基团为侧链的不对称结构的二芳基乙烯类光致变色化合物,两个目标化合物均可在光照的条件下进行光致异构化反应,并具有良好的光化学性质。结论 通过有机合成获得的两个新型二芳基乙烯类光致变色化合物均具有良好的光化学性质,为其在分子开关、生物医学领域的应用奠定基础。
英文摘要:
      Objective The asymmetric diarylethene photochromic compounds with benzo[b]thiophene as alkene bridge and naphthalene and 2-phenylthiazole as side chains were designed and synthesized.Their application prospects were well demonstrated according to the photochemical property investigation.Methods The target photochromic compounds were synthesized by classical organic synthesis methods and purified by thin-layer chromatography and column chromatography.Their chemical structures were characterized by 1H NMR.Finally,their photochromic properties of target compounds were investigated by ultraviolet-visible spectrophotometer to elucidate their application prospects.Results Two novel asymmetric diarylethene photochromic compounds with naphthalene group as side chain were obtained.Both of them can undergo photoisomerization reaction under light irradiation and reveal excellent photochemical properties.Conclusion The two photochromic compounds obtained by organic synthesis exhibit admirable photochromic properties and establish the foundation for their applications in molecular switch and biomedical fields.
