β-Cyclodextrin Complexes of Polymers Containing Aromatic Groups

摘要: Cyclodextrins (Cdx) are cyclic oligosaccharides consisting of six (α-CDx), seven (β-CDx), or eight (γ-CDx) D-(+)-glucopyranose units linked by α-(1,4) bonds. The presence a central cavity with hydrophobic properties makes these molecules able to form inclusion complexes organic inorganic substrates. This fact opened the way applications in many different fields, such as pharmacology, food science, analytical chemistry, and chemical synthesis catalysis [1–6]. wide variety low weight compounds [3]. However, guest have been limited small molecules, which can fit cyclodextrins. Inclusion complex formation has studied methods. Among methods, 1H NMR spectroscopy, UV-visible CD method considered be most popular. But only few literature about interactions between β-cyclodextrin polymers aqueous solution were reported. It particularly concerns Harada’s studies who found that cyclodextrins polymers, poly(ethylene glycol) [7–8], poly(propylene [9–10], poly(methyl vinyl ether) [11], polyisobutylene [12], crystalline state. Only one study polyamine was realized [13]. In our laboratory, covalent non cyclodextrin-polyvinylamine system [14]. investigations medium more complicated carry out, because problems may arise from solubility high viscosity. present study, we used Poly (4-sodium styrenesulfonate) NaPSS is polymer doesn’t take any compact structure solution. extended chain allows aromatic groups easily accessible moieties. investigated measuring changes circular dichroism spectra. Then probable considering data. Furthermore, viscosimetry induced also investigated.
