杯芳烃是重要的超分子试剂,其同系物的吸收光谱重叠严重,难以直接同时测定。本文应用主成分回归法研究了对叔丁基杯[4]芳烃、对叔丁基杯[6]芳烃和对叔丁基杯[8]芳烃三种大分子同系化合物组成的混合体系中各组分同时直接测定,测定结果回收率为94%-111%,具有较高的准确度,且过程简单,运算快速,为同系物混合体系的同时测定研究提供了新的途径。 Calixarenes are important supramolecular reagents. The absorption spectra of their homologues overlap seriously, making it difficult to measure simultaneously directly. In this paper, the principal components regression method was used to study the effects of p-tert-butylcalix [4] arene, p-tert-butylcalix [6] arene and p-tert- Points directly measured simultaneously, the determination of the recovery rate was 94% -111%, with high accuracy, and the process is simple, fast operation, simultaneous determination of the homologue mixture system provided a new way.
