摘　　要：从小分子出发通过一系列的合成步骤,最终合成了3,3-二甲基-N-乙基-6’-硝基苯并螺吡喃（SP1）、3,3-二甲基-N-乙基-5-氯-6’-硝基苯并螺吡喃（SP2）和3,3-二甲基-N-乙基-5-甲氧基-6’-硝基苯并螺吡喃（SP3）3种未见文献报道的螺吡喃。通过元素分析、红外光谱、核磁共振等手段对合成的部分中间体和目标产物的结构进行表征,并应用紫外-可见吸收光谱对其光致变色性进行了研究。Three indolinspiropyran monomers which were not seen before were synthesized with small molecules.They were 3,3-dimethyl-N-ethyl-6＇-nitro-indolinospiropyran（SP1）,3,3-dimethyl-N-ethyl-5-chloro-6＇-nitro-indolinospiropyran（SP2）,3,3-dimethyl-N-ethyl-5-methoxyl-6＇-nitro-indolinospiropyran（SP3）.The structures of titled compounds and some intermediates obtained were identified by elemental analysis,IR and 1HNMR.And their photochromic properties were studied by UV-Vis absorbance spectra.
