A new 3D zinc-organic framework of [ZnL]·5H₂O (1, K₂L = potassium 4′-furyl-2,2′:6′,2″-terpyridine-4,4″-dicarboxylate) has been synthesized under hydrothermal conditions. Complex 1 possesses a 3D 2-fold interpenetrated 4-connected sra network with pores decorated by noncoordination furan rings, and it exhibits a broad blue luminescence emission band peaked at 450 nm. Due to the chelating effect of trepyridyl moieties in L^2– ligands and the absence of solvent coordination sites on Zn(II), complex 1 exhibits a good thermal and acid-proof stability, and can be directly carbonized at 1000 °C under argon atmosphere into a new microporous carbon material C1000. The gas adsorption properties of desolvated 1a and microporous carbon C1000 have been studied by N₂ and CO₂ sorption measurements.
