Syntheses and characterizations of two-dimensional polymers based on tetraimidazole tetraphenylethylene ligand with aggregation-induced emission property

摘要

Two new coordination polymers [Co(TIPE)(H2O)2]-Hbtc-CH3CN-3H2O (1) and [Cd(TIPE)_(0.5)(m-bdc}(H2O)]-CH3OH-H2O (2) (TIPE = tetra(3-imidazoylphenyl)ethylene, H3btc = 1,3,5-benzenetricarboxylate, m-H2bdc = 1,3-benzenedicarboxylate) have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, elemental analysis, IR, TGA, and PXRD. Furthermore, the luminescent properties of complexes 1,2 and TIPE ligand have also been investigated in the solid at room temperature.
