本文通过主体分子环糊精(CD)和客体分子二茂铁(Fc)之间的包结络合作用,在CD稳定的CdS量子点(CD@QD)表面成功地引入了可聚合双键.所得超分子结构能够作为交联点与N,N-二甲基丙烯酰胺(DMA)单体共聚制备杂化超分子水凝胶(Fc-Gel),称为超分子交联点(Fc-SCL).Fc还赋予了该结构良好的电化学敏感性.随着Fc-SCL含量的增加,Fc-Gel的力学性能有所增强.此外,该凝胶还具有良好的荧光性质.实验表明,在凝胶形成过程中,CD和Fc之间的包结络合起了关键的交联作用,因此这种凝胶是一种由超分子作用诱导的有机-无机杂化水凝胶.
In this paper, a polymerizable double bond was successfully introduced onto CD-stabilized CdS quantum dots (CD @ QDs) surface by the entrapment complexation between the host molecule CD and guest ferrocene (Fc). The resulting supramolecular structure can be used as a cross-linking point to copolymerize with N, N-dimethylacrylamide (DMA) monomer to prepare a hybrid superamolecular hydrogel (Fc-Gel) ) .Fc also gives good electrochemical sensitivity of the structure.With the increase of Fc-SCL content, Fc-Gel mechanical properties have been enhanced.In addition, the gel also has good fluorescence properties.Experiments show that in the During gel formation, the inclusion complex between CD and Fc plays a critical cross-linking role. Therefore, this gel is a supramolecular-induced hybrid of organic-inorganic hybrid hydrogels.
