C60吲哚衍生物与对叔丁基杯[8]芳烃包合作用的热力学研究
The Modynamic Study on Supramolecular Complex of C60-indole Derivative with p-tert-butylcalix [8] arene
【摘要】 用紫外光谱分析法,研究了对叔丁基杯[8]芳烃与C60-吲哚衍生物形成包合物的能力,测定了C60衍生物与杯[8]形成的包合物的形成常数、热力学函数ΔH和ΔS.结果表明:C60上取代基空间阻力使形成配合作用减弱,形成常数减小,焓值和熵值都正移.
【Abstract】 Supra molecular Complexation or C60-indole derivative with p-tert-butylCalix[8]arene is studied by UV-Vis.The formation constants(Kassoc)and the the modynamic parameters (ΔH?ΔS)are decided. The expertmental results showed with the space resistarne increasing, the attractive interation between C60-indole Derivative and Caxlix[8]arene weaked, the formation constant( K)decreased and ΔH orΔS shifted positively.
