文摘

Reaction of 2,3,6,7,10,11-hexaaminotriphenylene with Ni²⁺ in aqueous NH₃ solution under aerobic conditions produces Ni₃(HITP)₂ (HITP = 2,3,6,7,10,11-hexaiminotriphenylene), a new two-dimensional metal鈥搊rganic 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路cm^鈥?, respectively, both records for MOFs and among the best for any coordination polymer.
