A novel pillared-layer Cd-MOF was synthesized as luminescent sensor for detection of nitroaromatic explosives with highly selective and recyclable properties. The study also shows that the photoinduced electron transfer and resonance energy transfer were possible mechanisms of fluorescence quenching.
