摘　　要：以1,6-己二醇、2,4-二羟基苯甲醛和罗丹明B为原料,设计合成了含罗丹明结构的单体M1,其结构经1H NMR和质谱表征。利用紫外光谱研究了M1在Ni2+离子存在下的光致变色效应。结果表明:M1-Ni2+溶液有弱的可见吸收呈浅红色,经365 nm紫外光照射后,转为深红色并在551 nm产生强的吸收。停止照射后溶液又能转变为浅红色,具有良好的光致变色性能。Using 1,6-hexandiol,2,4-dihydroxybenzaldehyde and rhodamin B as main raw material,the monomer M1 was designed and synthesized through a series of reaction,and its structure was characterized by 1H NMR,MS spectra.The photochromic properties of the monomer M1 with nickel ions have been investigated in EtOH solution by the ultraviolet spectrophotometry.The results indicated that nickel-M1 complex had weak absorption in the region of visible light and looked like light red,but on irradiation of 365 nm UV,the solution had an intensive absorption at 551 nm and gave a deep red color.When stopping irradiation the solution returned light red,indicating a good photochromic property.
