Syntheses, structures and properties of metal-carboxylate chain-based coordination polymers (CPs) with 1,1′:4′,1″-terphenyl-2′,4,4″,5′-tetracarboxylate

Abstract Two coordination polymers (CPs) {[Mg 2 L( μ 2 -H 2 O) ( μ 2 -DMA)]·DMA} n ( 1 ), and [Ag 4 L(DMF) 2 ] n ( 2 ) (H 4 L = 1,1′:4′,1″-terphenyl-2′,4,4″,5′-tetracarboxylic acid, DMA = N,N-dimethylacetamine, DMF = N,N-dimethylformamide) have been synthesized and structurally characterized. In 1 and 2 , there exist a series of parallel aligned M O C chains, which are linked along two directions by para-terphenyl moieties of L 4− ligands to lead to the metal-carboxylate chain-based three-dimensional frameworks. The photoluminescence properties of the compounds 1 and 2 have also been investigated. 1 displays blue-violet light emission with the emission maximum at 380 nm. 2 exhibits a broad emission peak from 300 to 800 nm with an emission maximum at 484 nm and some of the shoulder peaks.
