Synthesis, structure and properties of luminescent Cd(II) coordination polymers based on imidazole-decorated tetraphenylethylene

Two new cadmium(II) luminescent coordination polymers (CPs), [Cd(L)Cl 2 ]·3DMF (1) and [Cd(L)(DMA)(H 2 O](ClO 4 ) 2 ·5DMA (2) (L = 1,1,2,2-tetrakis(4-(1H-imidazol-1-yl)phenyl)ethene, DMF = N,N-dimethylformamide, DMA = N,N-dimethylacetamide), were synthesized under solvothermal conditions.

Description
Summary:Two new cadmium(II) luminescent coordination polymers (CPs), [Cd(L)Cl 2 ]·3DMF (1) and [Cd(L)(DMA)(H 2 O](ClO 4 ) 2 ·5DMA (2) (L = 1,1,2,2-tetrakis(4-(1H-imidazol-1-yl)phenyl)ethene, DMF = N,N-dimethylformamide, DMA = N,N-dimethylacetamide), were synthesized under solvothermal conditions. Crystallographic analyses reveal that 1 and 2 have different two-dimensional (2 D) network structures. Both 1 and 2 show mechanochromic properties with fluorescent color change from blue to blue-green under UV light. In addition, 1 can be potentially utilized as mechanochromic material as well as a sensor for detection of DMF, exhibiting reversible mechanochromic luminescence with color changes and self-repairing behavior by grinding and soaking in DMF under UV irradiation. Furthermore, 1 can act as potential fluorescence materials for sensing Fe(III).
