A highly fluorescent metal-organic framework (In-MOF, In(OH)bpydc (bpydc = biphenyl-5,5'-dicarboxy late)) imparting additional luminescent Eu3+ ions has been synthesized for sensing organic molecules and anions, especially chloroform and MnO4- both of them have a significant spectral response. This Eu-3(+)-incorporated hybrid (In-MOF-Eu) has been fully characterized, which reveals large surface area, great pore size, favorable thermal stability, excellent luminescence as well as good fluorescence stability. On the one hand, the dual-emitting MOF hybrid exhibits a distinctly different response to the chloroform, one of which is almost unchanged, while the other intrinsic broad emission has a remarkable enhancement, leading to an obvious change in color; on the other hand, it also shows a high selectivity for detection of MnO4- because of the largest quenching effect on the luminescent emission, which results in a dark emission. This work represents a new approach for the fabrication of highly selective and sensitive probe for detection of chloroform and MnO4-, as it underlines the opportunity of MOFs with prominent optical properties to explore the existing target substance in the environment.
