Design and Construction of a Metal–Organic Framework as an Efficient Luminescent Sensor for Detecting Antibiotics

This is the authors' abstract. We don't add key points for this paper.

We first design and synthesize a dendritic aromatic 6-carboxyl linker (H 6 TDCPB), which is successfully assembled with Cd(II) ion to construct a porous metal–organic framework with a raw Cd 6 cluster, {[Cd 3 (TDCPB)·2DMAc]·DMAc·4H 2 O} 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.
