A Chemiluminescent MetalâOrganic Framework
The synthesis and characterization of a chemiluminescent metalâorganic framework with high porosity is reported. It consists of Zr6O6(OH)4 nodes connected by 4,4â˛â(anthraceneâ9,10âdiyl)dibenzoate as the linker and luminophore. It shows the topology known for UiOâ66 and is therefore denoted PAPâUiO. The MOF was not only obtained as bulk material but also as a thin film. Exposure of PAPâUiO as bulk or film to a mixture of bisâ(2,4,6âtrichlorophenyl) oxalate, hydrogen peroxide, and sodium salicylate in a mixture of dimethyl and dibutyl phthalate evoked strong and long lasting chemiluminescence of the PAPâUiO crystals. Time dependent fluorescence spectroscopy on bulk PAPâUiO and, for comparison, on dimethyl 4,4â˛â(anthraceneâ9,10âdiyl)dibenzoate provided evidence that the chemiluminescence originates from luminophores being part of the PAPâUiO, including the luminophores inside the crystals
