Design and Construction of a Metal–Organic Framework as an Efficient Luminescent Sensor for Detecting Antibiotics
2020
We first design and synthesize a dendritic aromatic 6-carboxyl linker (H6TDCPB), which is successfully assembled with Cd(II) ion to construct a porous metal–organic framework with a raw Cd6 cluster, {[Cd3(TDCPB)·2DMAc]·DMAc·4H2O}n (namely, complex 1). More interestingly, six adjacent linkers are packed together by π–π-stacking interactions to form an amazing six-molecule accumulation in the crystal structure. By virtue of high stability and luminescent properties, the as-synthesized sample not merely owns an excellent detectable ability but also possesses an outstanding selectivity for nitrofurans with remarkable recursitivity.
