用苄基（Bz）部分修饰的聚丙烯酰胺（pAAm）基凝胶（Bi（x）-凝胶，其中x表示Bz部分的mol %含量）与具有环糊精（CD）部分的pAAm基凝胶（α CD-凝胶、β CD-凝胶和γ CD-凝胶）的相互作用。在不同的温度下进行了研究，以阐明温度对宏观组装体形成的影响。Bz（x）-凝胶与CD-凝胶的相互作用在较低温度下更强，与用1 mol % Bz部分修饰的pAAm和天然CD的模型系统的结合常数一致。Bz（15）-凝胶仅在较高温度下与β CD-凝胶相互作用（
The interaction of polyacrylamide(pAAm)-based gel modified with beniyl (Bz) moiety (Bi(x)-gel, where x denotes the mol % content of Bz moiety) with a pAAm-based - gel possessing cyclodextrin (CD) moieties (alpha CD-gel, beta CD-gel; and gamma CD-gel). was investigated at various temperatures to elucidate the effect of temperature on the formation of macroscopic assembly. The interaction of Bz(x)-gel with CD-gels was stronger at a lower temperature, consistent with the binding constants for the model system of pAAm modified with 1 mol % Bz moiety and native CDs. Bz(15)-gel interacted only with beta CD-gel at a higher temperature (
