Abstract
A novel three-dimensional microporous metal-organic framework (MOF), Cd 3(CTC) 2(TED)(H 2O) 2 · (H 3O) 2Cl 2 ( 1) (H 3CTC = cis, cis-1,3,5-cyclohexanetricarboxylic acid and TED = triethylenediamine), has been synthesized under mild condition with mixed H 3CTC and TED ligands. It is of particular interest that twofold alternate (6,3) net subunits constructed from Cd centers and H 3CTC ligands are supported by linear TED ligands along the c axis to build a 3D architecture. This structure exhibits about 7.2 × 8.4 Å 2 channels along the [100] direction. The water adsorption isotherm shows type I behavior with approximately 0.07 mL/g pore volume. The fluorescent emission spectrum of polymer 1 shows a sharp blue-shift peak at 522 nm ( λ ex = 235 nm).
