摘要
合成了环糊精二聚体(trans-Azoβ-CD Dimer)及侧链含金刚烷(Ad)的聚丙烯酰胺(PAM-Ad),利用trans-Azoβ-CD Dimer与PAM-Ad侧链的Ad基团的主客体识别作用构筑了一类超分子体系。2D NMR测定结果表明,trans-Azoβ-CD Dimer和PAM-Ad的主客体相互作用是通过β-CD空腔和疏水体Ad形成包结络合物进行的。环糊精二聚体trans-Azoβ-CD Dimer和聚合物PAM-Ad两者之间的缔合程度受trans-Azoβ-CD Dimer和PAM-Ad的浓度、温度、盐浓度以及trans-Azoβ-CD Dimer光异构的影响。
Cyclodextrin dimer( trans-Azo β-CD Dimer) and adamantyl modified polyacrylamide( PAM- Ad) were synthesized. A supramolecular system was constructed by the formation of inclusion complex between trans-Azo β-CD Dimer and PAM-Ad. The results of 2D NMR measurement indicate that the host-guest interaction between trans-Azo β-CD Dimer and PAM-Ad was carried out through the formation of inclusion complexes between β-CD cavity and the hydrophobe Ad. The interaction between trans-Azo fl-CD Dimer and PAM-Ad depended on the concentration of trans-Azo β-CD Dimer, PAM-Ad and the photoisomerization of trans-Azo /3-CD Dimer. The influences of salt concentration and temperature on the viscosity of the mixture solution were also studied.
