摘要
研究了一种长链烷氧基希夫碱类凝胶因子H1的成凝胶能力及其刺激响应性能。实验结果表明,H1可在甲醇和乙腈中形成稳定的有机凝胶OG。向OG中加入F^-、Ac^-、H2PO4^-后,凝胶塌陷,当向其中加入Ni^2+、Mn^2+、Zn^2+、Pb^2+、Cu^2+、Ag+、Co^2+、K+等多种金属离子后,Ni^2+、Mn^2+、Zn^2+、Co^2+、K^+5种离子可以破坏凝胶体系,Pb^2+、Cu^2+、Ag+3种离子则形成了稳定的金属有机凝胶MOG。运用SEM可观察到有机凝胶OG呈现出片状带孔洞结构,金属有机凝胶呈现出带有孔洞的片状结构。采用XRD、红外等技术手段推测出形成凝胶的主要作用力可能为氢键、长烷基链疏水作用、π-π堆积及范德华力。
This paper studied the gelation ability and stimuli response of a long-chain alkoxy Schiff base-like gelator(H1).The experimental results showed that H1 can form a stable organic gel(OG)in methanol and acetonitrile.After adding F^-,Ac^-,and H2PO4-to the organogel,the gel collapsed.With various metal ions Ni^2+,Mn^2+,Zn^2+,Pb^2+,Cu^2+,Ag+,Co^2+,K^+,the gel collapsed followed by Ni^2+,Mn^2+,Zn^2+,Co^2+,K^+.However,the gel formed a stable metal organogel(MOG)followed by Pb^2+,Cu^2+and Ag+ions.It can be observed that the organogel(MOG)exhibits a flake-like with pore structure,and the organometallic gel exhibits a flake-like structure with pores by SEM.Using XRD,IR and other technical means to speculate that the main force to form a gel may be hydrogen bonds,long alkyl chain hydrophobic effect,π-πstacking and Van der Waals force.
