A solar light-active copper-metal organic framework (Cu-MOF) was constructed through a multiple-linker strategy employing 1,2,4,5-benzenetetracarboxylic acid (H4btec) and 4,4′-bis(1-imidazolyl)biphenyl (bimb) as ligands. A reaction mixture consisting of ligands and Cu-metal salts was heated to a critical point in a hydrothermal reactor. The constructed MOF was studied for materials chemistry through

strongly decreased only in the presence of Hg2+ ions. The order of the stability constants of 1:1 podands–Hg2+ complexes is in the order: 52 > 53 > 35> 31> 32> 36> 33. On the other hand, podands 34 and 54 formed 1:2 podands–Hg2+ complexes. Thiacrown ethers 14-16, 18-22 and acyclic thiacrown ethers 31-36, and 52-57 were evaluated against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes
An indole-azadiene conjugate (1), synthesized by facile one-step condensation, behaves as a highly selective probe for detection of fluoride ion both in colorimetric and fluorometric analyses. The probe 1 shows F−-selective color change from colorless to yellow and appearance of green fluorescence. 1H NMR analysis and ab initio calculation reveal that the F−-induced colorimetric and fluorometric responses of 1 are simply driven by hydrogen bonding interaction between the indolic NH protons and F−.
