Abstract
Solvothermal reaction of cadmium nitrate with a polypyridine-containing ligand tetra(pyridine-4-yl)benzene-1,4-diamine (TBD) gives rise to a novel Cd(II)-organic framework with the 3D interpenetrated architecture [Cd(TBD) (NO 3 ) 2 ·DMA]( 1 ) (DMA = N, N -dimethylacetamide). The stability test is performed on compound 1, which shows that the Cd-MOF can be quite stable in water and even harsh conditions. A photoluminescence study has been investigated on 1 . Remarkably, nitrofurantoin, as a kind of antibiotic, has a great quenching effect on the luminescent performance of the prepared hybrid, suggesting that compound 1 can be regarded as an effective chemical sensor to detect specific analytes. The anti-interference test, recyclability examination, and sensing mechanism have been further conducted. Moreover, in virtue of the electron transfer from oxygen of NO 3 – to nitrogen atoms of TBD, photochromism behavior can be easily realized in compound 1 .
