A microporous material constructed by pi-pi interaction of a twisted H-shape poly-aromatic molecule, 1,4-bis(3,6-diphenylpyridazin-4-yl)benzene (1) was synthesized and X-ray quality crystals were isolated. The intermolecular distances between the various aromatic rings are within the range of 3.4 similar to 3.7 angstrom, which indicate intermolecular pi-pi interactions. Hexagonal channels with pores of 13 angstrom width along the c-axis were observed. Interstitial H2O and MeOH molecules were located within each porous channel.
