英文摘要以对羟基苯甲酸(4-HBA)为模板分子,4-乙烯吡啶(4-Vpy)为功能单体,制备得到了4-HBA分子印迹聚合物P(4-HBA),研究了该聚合物的分子识别机理,并与在同样条件下制备的水杨酸(SA)分子印迹聚合物P(SA)进行了分子识别能力的比较.结果表明:P(SA)比P(4-HBA)具有更好的分子识别能力.这是由于SA的酸性较4-HBA强,因此与碱性功能单体4-Vpy之间的静电作用更强,从而得到的复合物更稳定.本实验结果证明:功能单.体与模板分子形成稳定的复合物是得到分子识别能力高的模板聚合物的前提条件.本文将有助于对分子印迹的过程以及分子印迹聚合物分子识别机理的进一步理解,并且对于根据模板分子的性质预测MIP的分子识别能力也将具有一定的指导意义; A molecularly imprinted polymer (MIP) for 4 - hydroxybenzoic acid [ P(4 - HBA)] was prepared using 4 - vinylpyridine (4 - Vpy) as a functional monomer. Its molecular recognition mechanism was studied. And a comparison was made to evaluate its molecular recognition ability with that of salicylic acid - imprinted polymer E P(SA) I. The result shows that the molecular recognition ability of P ( SA) is higher than that of P(4 - HBA). The reason is that SA is stronger than 4 - HBA in acidity and SA can form a more stable complex with 4 - Vpy, which makes P(SA) have a higher molecular recognition ability. This study confirms that it is a prerequisite that the template should form a stable complex with the functional monomer in the preparation of MIP in order to obtain a MIP with high molecular recognition ability. Furthermore, this study will be helpful for us to understand the mechanism of molecular imprinting and molecular recognition of MIN. Also, it will be of instructive significance for us to predict the selectivity of MIPs according to the properties of templates.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000171884400019&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 3; 10; 1623-1627; 59
