| 摘 要： | 用聚氧乙烯辛基酚醚(OP)作荧光探针研究了OP和β-环糊精(β-CD)的相互作用.结果表明,OP分子的正辛基基团和苯基基团被包络在β-CD空腔内;用1-溴代萘(BN)分子作磷光探针进一步考察了OP与β-CD分子的缔合方式及对BN分子所产生的空间效应,OP分子的正辛基以绕曲的方式位于β-CD空腔中,因空间效应使β-CD空腔进一步包络BN的能力下降.

| Abstract: | Association of polyoxyethylene n-octylphenol ether(OP) with β-cyclodextrin(β-CD) was investigated using OP as a fluorescent probe. The results show that the n-octyl with phenyl ring was entrapped into the cavity of β-CD. 1-bromo-naphthaline (BN) was further employed as a phosphorescent probe to monitor the binding site of OP and the spatial effect of OP on BN. The n-octyl chain of OP was located in the cavity of β-CD in a compressed manner. As a result, the binding strength of BN to the β-CD cavity occupied by OP decreases due to the geometric considerations. |
