The trace detection of biomarkers in real samples has profound a most important significance the early diagnosis and daily monitoring diseases. Based on ligand pre‐design strategy, novel 3D CuMOF, with formula {[Cu 4 (BTPB)( μ 2 ‐OH) (H O) 5 ]·3H O} n , was fabricated by using hexacarboxyl 1,4‐bis(2,4,6‐tricarboxylpyrid‐5‐yl)benzene 6 BTPB) tetranuclear {Cu (COO) ( } SBUs. Benefiting from robust framework unique luminescence performance, prepared CuMOF displays great potential as dual‐responsive efficient luminescent sensor “turn‐off” 3‐nitrotyrosine (3‐NT) biomarker “turn‐on” detecting anthrax dipicolinic acid (DPA), limits (LOD) for 3‐NT DPA being 110.8 ng/ml 85.2 ng/ml, respectively. Additionally, practicality compatibility such developed sensors were verified quantifying diluted serum urine satisfactory recoveries. Further, theoretical calculations energy levels well spectral overlap between analytes conducted to elucidate possible sensing mechanisms. This work demonstrated that MOFs‐based are evolving an efficacious equable approach samples.

Acridone, a cyclic analogue of benzophenone that undergoes efficient intersystem crossing (ISC) to the triplet-excited state with near-unity quantum yield, was elaborated as 3-connecting triacid linker, i.e., H3AcTA, develop photocatalytic metal–organic framework (MOF) for energy transfer applications; linker inherently features concave shapes, an attribute is important construction MOFs significant porosity. Metal ion (Zn2+)-assisted self-assembly yielded Zn-MOF, Zn-AcTA, solvent-accessible volume ca. 31%. The protection acridone chromophore in MOF conjunction wider cross-section its absorption visible region renders excellent heterogeneous photosensitizer singlet oxygen (1O2) generation by ground-state triplet (3O2). It shown Zn-MOF can be applied photosensitizing catalyst light-mediated oxidation various sulfides sulfoxides and enaminones amino-esters via 1,2-acyl migration. further demonstrated photocatalyst easily recycled without any loss catalytic activity structural integrity. Based on mechanistic investigations, 1O2 established reactive species reactions. results constitute first demonstration rational development based oxidations mediated 1O2.
