基于有机自组织的质子传导材料研究进展

Advances in Organic Self-Assembly Based Proton-Conducting Materials

分子可通过相分隔、静电和氢键等作用形成特定微观结构的自组织。氢键或磺酸基、咪唑等官能团在有机材料中自组织后会形成空间连续分布的质子传递通道,通过Grutthuss机理或运载机理实现稳定的质子传导。基于不同的自组织及传导机理,有机质子传导体系可由共混物或单组分构建。评述了有机自组织在质子传导材料中的研究进展,并对双亲聚合物-水体系、酸-碱对共混物、嵌段共聚物、有机-无机复合体和液晶材料的质子传导特性进行了比较。

Molecules can form a self-assembly defined microstructure by phase segregation,static and hydrogen bonding effects.Self-organization of hydrogen bonding or functional groups such as sulfonic acid and imidazole in organic materials will form continuous proton-conducting pathways to transfer protons stably by Grutthuss or Vehicle mechanism.Proton conduction can be achieved either in multi-components systems or in pure chemicals.Advances in proton-conducting materials based on organic self-assembly are reviewed.Performance of amphipathic polymer-water systems,acid-base composites,block copolymers,organic-inorganic composites and liquid crystals are also outlined.
