摘要
设计和合成了一种新的基于C60 富勒烯部花菁化合物 2 ,用质谱、核磁共振谱、红外光谱和紫外光谱对化合物2进行了表征 .并对化合物 2的变色过程进行了研究 ,发现该化合物对极性溶剂如甲醇、N ,N 二甲基甲酰胺和酸或碱如乙酸、乙醇钠等具有良好的变色过程 .但由于部花菁染料受C60 的影响 ,其对光的灵敏度降低 ,光致变色过程非常缓慢 .
A new compound of merocyanine dye based on [60] fullerene unit (2) was designed, synthesized and characterized by MALDI-TOF, FT-IR, NMR and UV-vis spectra and the allochroic processes were also studied. Compound 2 had allochroic processes in polar solvents such as methanol or DMF. Acids or alkali such as acetic acid or NaOC2H5 also showed apparent influence on the allochroic process. The photochroic process was much slower than that of merocyanine dye itself due to the influence of [60] fullerene unit on the merocyanine moiety.
