Modulating the luminescent performances on blue-emitting coordination polymers via tuning the end-solvent molecules

Abstract

In this paper, a series of coordination polymers, {[Zn(adb)(L1)2]·solvent}n (L1 = solvent = N,N-dimethylacetamide, Hui-3-DMA; L1 = N,N-dimethylformamide and no solvent, Hui-3-DMF; L1 = N,N-diethylformamide and no solvent, Hui-3-DEF) have been synthesized by hydrothermal reactions of Zn(NO3)3·6H2O and 4,4′-(anthracene-9,10-diyl)dibenzoic acid (H2adb). These compounds show similar one-dimensional (1D) zig-zag chain structures, which are limited by the end-coordination of the solvent molecules. Interestingly, these compounds all show blue-emission properties, which could be easily modulated by using different solvents. Among them, Hui-3-DMA presents an excellent quantum yield performance, as high as to 54.1%, which is very promising for blue-emission materials. Moreover, various-temperature fluorescence studies reveal good linear or exponential decline trends for their emission intensity as temperature increases, demonstrating the potential of these compounds as fluorescent thermometers.
