Linking of highly conjugated tricatecholate, 2,3,6,7,10,11- hexahydroxytriphenylene (H 12C 18O 6, HHTP), with Co(II) and Ni(II) ions into two-dimensional porous extended frameworks, was demonstrated. These new crystalline materials, termed metal-catecholates (M-CAT), were characterized and their high chemical stability, thermal stability, and porosity, was determined. CATs were prepared by combining 1 equivalent of HHTP with 2 equivalents of the respective metal(II) acetate hydrated in an aqueous solution, and heating at 85°C for 24 h to give needle-shaped crystals. The images showed uniform morphology with hexagonal rods whose lengths are less than 10 μm and widths are only around 100 nm. The conductance of two different crystals of Cu-CAT-1 was calculated to be 1.8 × 10 -1 and 2.1 × 10 -1 S cm -1, respectively.
