在好氧条件下，2，3，6，7，10，11-六氨基三苯基与Ni2+在氨水溶液中反应生成了一种新型的二维金属有机骨架--Ni-3(HITP)(2)(HITP=2，3，6，7，10，11-六氨基三苯基)。这种新材料可以分离为高导电性的黑色粉末或暗蓝紫色薄膜。双探头和范德堡电学测量显示，体相(颗粒)和表面(膜)的电导值分别为2和40 S.cm(-1)，这两个值都是MOF的记录，在任何配位聚合物中都是最好的。
Reaction of 2,3,6,7,10,11-hexaaminotriphenylene with Ni2+ in aqueous NH3 solution under aerobic conditions produces Ni-3(HITP)(2) (HITP = 2,3,6,7,10,11-hexaiminotriphenylene), a new two-dimensional metal-organic framework (MOF). The new material can be isolated as a highly conductive black powder or dark blue-violet films. Two-probe and van der Pauw electrical measurements reveal bulk (pellet) and surface (film) conductivity values of 2 and 40 S.cm(-1), respectively, both records for MOFs and among the best for any coordination polymer.
