Abstract

Complexation reactions between 1-amino-9,10-anthraquinone (AA1), 1-amino-2-methyl-9,10-anthraquinone (AA2), 1-amino-2,4-dimethyl-9,10-anthraquinone (AA3) and 1-amino-2-ethyl-9,10-anthraquinone (AA4) and beta-cyclodextrin were studied spectrofluorometrically, under optimized experimental conditions. The formation constants of the resulting 1:1 beta-cyclodextrin complexes were evaluated and found to decrease in the order AA4>AA1>AA3>AA2. Possible reasons for the observed stability sequence are discussed based on the structures proposed for the resulting inclusion complexes.

摘要

在优化的实验条件下，采用荧光光谱法研究了1-氨基-9,10-蒽醌（AA1）、1-氨基-2-甲基-9,10-蒽醌（AA2）、1-氨基-2,4-二甲基-9,10-蒽醌（AA3）和1-氨基-2-乙基-9,10-蒽醌（AA4）与β-环糊精之间的络合反应。评估了所得1:1 β-环糊精络合物的形成常数，发现其顺序为AA4>AA1>AA3>AA2。根据所得包合物的结构，讨论了观察到的稳定性顺序的可能原因。
