Three coordination polymers (CPs) have been synthesized based on a [Co(bpy)(H2O)4]2+ chain (bpy=4,4′‐bipyridine) by a template approach. The frameworks are neutralized by different templated polycarboxylate anions (furan di‐carboxylate (fdc) in Co‐fdc, benzene tri‐carboxylate (btc) in Co‐tri and benzene tetra‐carboxylate (btec) in Co‐tetra). These templates with different degrees of protonation and ionic carrier concentration played significant role on crystal packing as well as formation of well‐directed H‐bonded networks which made these CPs perform well in proton conduction (PC). The PC value reaches to 1.49×10−1 S cm−1 under 80 °C and 98 % relative humidity (R.H.) for Co‐tri, which is the highest among CPs/MOFs/COFs and is an example of conductivity in the order of 10−1 S cm−1. Co‐tri and Co‐tetra are excellent proton conductors at mild temperature (40 °C) and 98 % R.H. (conductivities up to 2.92×10−2 and 1.38×10−2 S cm−1, respectively).

聚羧酸酯模板配位聚合物:模板在高达10-1 S cm-1的超质子电导率中的作用

通过模板方法,基于[Co(bpy)(H 2 O)4 ] 2+链(bpy = 4,4'-联吡啶)合成了三种配位聚合物(CP)。框架被不同的模板化多羧酸根阴离子(Co-fdc中的呋喃二羧酸根(fdc),Co-tri中的三羧酸苯(btc)和Co-tetra中的四羧酸苯(btec))中和。这些具有不同质子化程度和离子载流子浓度的模板在晶体堆积以及形成良好定向的H键网络方面起着重要作用,这使得这些CP在质子传导(PC)中表现良好。PC值达到1.49×10 -1  S cm -1Co-tri在80°C和98%的相对湿度(RH)下处于最高温度,是CP / MOF / COF中最高的,并且是电导率约为10 -1  S cm -1的示例。Co-tri和Co-tetra是在温和的温度(40°C)和98%RH(电导率分别高达2.92×10 -2和1.38×10 -2  S cm -1)下的优良质子导体。
