摘　　要：杂多酸型离子液体是近年来逐渐发展起来的一类新颖的有机-无机杂化材料,但目前在阳离子离子液体的合成工艺上均采用有毒、昂贵的磺酸内酯作为磺化剂以进一步提高离子液体的电导率。因此文中采用一种无毒、绿色、环保的合成路径合成了新型酸性离子液体[1-(2-羟基-3-磺酸基)丙基-3-丙基-咪唑盐],并分别与3种钼取代keggin型磷钨酸H3PW11MoO40(PW11Mo),H3PW9Mo3O40(PW9Mo3)和H3PW6Mo6O40(PW6Mo6)进行杂化制得3种不同的有机-无机杂化电解质材料。它们不仅具有较高的电导率(室温下高于10^-4 S/cm),还解决了杂多酸易潮解、稳定性差、易泄露等问题。该杂化手段极大地拓宽了杂多酸的电化学应用范围。The polyoxometalate-based ionic-liquids are the novel organic-inorganic hybrid material which has been gradually developed in recent years, but the sultone was widely used as the sulfonating agent to further improve electrical conductivity even they are toxic and expensive. So 1-(2-hydroxy-3-sulfonic acid) propyl-3-propyl imidazole salt(PIM-CHP) was used as the cation,and three molybdenum substituted keggin phosphotungstic acid H3PW11MoO40(PW11Mo), H3PW9Mo3O40(PW9Mo3) and H3PW6Mo6O40(PW6Mo6) was used as the anion to build three new organic-inorganic hybrid materials by a non-toxic, green and environmentally friendly method. They are not only exhibiting a high conductivity(>10^-4 S/cm at room temperature), but the disadvantages of heteropolyacids like high deliquescent and low stability were also overcame by hybridization. The hybridization greatly broadens the electrochemical applications of heteropolyacids.
