点击化学法合成1-(4-甲氧苄基)-4羟甲基-1,2,3-三氮唑

Synthesis of 1-(4-Methoxybenzyl)-4-hydroxymethyl-1,2,3-triazole with Click Chemistry

目前常见的全氟磺酸膜具有较高的质子传导率,但是由于其质子传导机理决定了在较低温度、高相对湿度下才显示出功能化,使其实际应用受到限制.以4-甲氧基苄醇为原料,通过氯代,叠氮取代和Click Chemistry环加成反应制备获得一种质子导体1-(4-甲氧苄基)-4-羟甲基-1,2,3-三氮唑,可用于制备新型聚合物电解质膜.该工艺环保、反应条件温和.通过FTIR与NMR对合成产物的结构进行鉴定,结果证实了本次合成路线的可行性,反应总收率为38.4%.

The development of novel electrolyte membranes with dense structure,good mechanical flexibility,and high proton conductivity,but with little or no dependence on humidity at temperatures above 100 ℃ remains an important challenge to the practical operation of PEMFCs.In this paper,1-（4-methoxybenzy-l）-4-hydroxymethyl-1,2,3-triazole（CTMOB）,one of the proton conducting species,was synthesised with Click Chemistry using 4-methoxybenzyl alcohol as the starting material.The structures of systhesized materials were characterized with FTIR and NMR.The results show that the proposed synthesis route of CTMOB is feasible and the total yield of CTMOB is 38.4%.
