Two new metal-organic open frameworks (MOFs) [Zn3L2(btc)(2)(H2O)]center dot(guests) (1), [CdL(bdc)]center dot(guests) (2), were successfully prepared by using a photoluminescent BODIPY-based bipyridine linker, L, and auxiliary ligands 1,4-benzenedicarboxylate (H(2)bdc) and 1,3,5-benzenetricarboxylate (H(3)btc), respectively. MOF 1 has a 2-fold interpenetrating three-dimensional (3D) framework with an 8-connecting body centered cubic (bcu) net, built upon a paddlewheel cluster [Zn-2(O2CR)(4)], a tetrahedrally connecting Zn and a 3-connected btc(3-) ligand. MOF 2 has a highly open framework with a kagome-type net. It is a pillared layered structure made of 2D [Cd(bdc)] kagome sheets and L as pillars. MOF 1 was shown to exhibit permanent porosity and adsorption of N-2, H-2, CO2 and CH4. Both MOFs exhibited strong photoluminescent emissions at room temperature with peaks at 540 nm upon excitation, owing to a ligand L-based excited state.
