新型金属-有机骨架[Zn 3 (Ni-H 2 TPPP)(Ni-H 4 TPPP)(Ni-H 5 TPPP)*7(CH 3) 2 NH 2 *DMF*7H 2 O]（其中Ni-H x TPPP （x=2,4,5）为部分去质子化[5,10,15,20-四（3-（膦苯基）-卟啉（2-））]镍（II）种），IPCE-2Ni具有优异的质子导电性（1.0×10 -2 S∙cm -1，在75°C和95%相对湿度下）。在IPCE-2Ni -独特的晶体结构中，高浓度的游离膦酸基团和由氢键结合的补偿二甲基铵阳离子是观察到质子电导率高的关键因素，该电导率比基于5,10,15,20-四(4-（膦苯基）-卟啉（2-）]镍（II） IPCE-1Ni的相应MOF高一个数量级，可与MOF中的领导者相媲美。
A novel metal-organic framework [Zn 3 (Ni-H 2 TPPP)(Ni-H 4 TPPP)(Ni-H 5 TPPP)*7(CH 3 ) 2 NH 2 *DMF*7H 2 O] (where Ni-H x TPPP (x=2,4,5) are partially deprotonated [5,10,15,20-tetrakis(3-(phosphonatophenyl)-porphyrinato(2-))]nickel(II) species), IPCE-2Ni , with outstanding proton conductivity (1.0×10 -2 S∙cm -1 at 75°C and 95% relative humidity) was obtained. The high concentration of free phosphonate groups and compensating dimetlylammonium cations bound by hydrogen bonds in the unique crystal structure of IPCE-2Ni -is a key factor responsible for the observed high proton conductivity that is one order higher that for corresponding MOF based on 5,10,15,20-tetrakis(4-(phosphonatophenyl)-porphyrinato(2-))]nickel(II) IPCE-1Ni and comparable with leaders among MOFs.
