在微波辐射下，通过1，3-偶极环加成反应，以适当官能化的肼为原料，在一锅中合成了一系列三元吡唑并[60]富勒烯。用循环伏安法对所得化合物的电化学性质进行了研究，发现它们在所有情况下都表现出比母体C(60)更好的电子受体特性。荧光实验和时间分辨跃迁光谱表明，存在以C(60)三重态为受主的光致电荷转移过程。
A series of triad pyrazolylpyrazolino[60]fullerenes has been prepared in one pot from suitably functionalized hydrazones by 1,3-dipolar cycloaddition reactions under microwave irradiation. The electrochemical properties of the compounds obtained were investigated by cyclic voltammmetry, and they show better electron acceptor character than the parent C(60) in all cases. Fluorescence experiments and time-resolved transition spectroscopy indicate the existence of photoinduced charge-transfer processes with the C(60) triplet acting as the acceptor.
