研究了对－叔丁基杯［８］芳烃（ｐ－ｔｅｒｔ－ｂｕｔｙｌｃａｌｉｘ［８］ａｒｅｎｅ）的红外和拉曼光谱，并与杯［４］芳烃的红外和拉曼光谱进行了比较．杯［８］芳烃与杯［４］芳烃都属于同一类寡聚物，其红外和拉曼光谱虽有某些相似但彼此之间存在着明显的差异．这些光谱特征的差异说明杯［８］芳烃八聚体的“折迭环”构象与杯［４］芳烃四聚体的“锥形”结构有着显著的差别． The infrared and Raman spectra of p-tert-butylcalix (8) arene were studied and compared with the infrared and Raman spectra of calix [4] arene. Both calix [8] arenes and calix [4] arenes belong to the same class of oligomers. Although their IR and Raman spectra are similar, there are obvious differences between them. The differences in these spectral characteristics indicate that the “folded loop” conformation of the calix [8] arene octamer is significantly different from the “conical” structure of the calix [4] arene tetramer.
