Formation of the charge-transfer complexes between various calix[4]crowns (1-4) and [60]fullerene were studied in toluene solution using UV-vis spectrophotometry. The stability constants and the thermodynamic data of the resulting 1:1 complexes were determined and were found to decrease with increasing the size of the crown moiety of the calixcrown. Except the complex of 3, all the complexes were found to be enthalpy stabilized but disfavored in terms of entropy.
利用紫外可见分光光度法研究了各种杯[4]冠醚（1 - 4）与[60]富勒烯在甲苯溶液中电荷转移配合物的形成。测定了所得1:1配合物的稳定常数和热力学数据，发现其随杯冠醚冠部分尺寸的增加而降低。除了3的配合物外，发现所有配合物都是焓稳定的，但在熵方面不利。
