设计和合成了一种新的基于C_(60)富勒烯部花化合物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。但由于部花莆染料受C_(60)的影响，基对光的灵敏度降低， 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 NaOC_2H_5 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.

Key words: C60, MS, 1HNMR, IR, STRUCTURE CHARACTERISTICS, PHOTOCHROMISM
