Реферат: Metal-organic frameworks (MOFs) are porous materials with promising gas adsorption, catalytic and sensing properties. Luminescent MOFs are especially perspective for sensing applications since the quenching or enhancement for the emission may be accurately measured and in most cases detected even by the naked eye allowing the development of portable test kits. The focus of our work is the introduction of highly emissive ligands into the structure of MOFs to achieve high quantum yields and selective luminescent response towards organic and inorganic pollutants. Thus, MOF {[Cd8(tr2btd)5(dcdps)8(H2O)(EtOH)]∙5DMF}n (H2dcdps = di(p carboxyphenyl)sulphone, tr2btd = 4,7-di(1,2,4-triazol-1-yl)-2,1,3-benzothiadiazole) demonstrated a high photoluminescence quantum yield of 70 % and a sensitive emission “turn-on” response towards Ga3+ cations (LOD 1.1 M) and a “turn-off” response to the cottonseed phytotoxicant gossypol (LOD 0.17 M). Water-stable and high-temperature resistant zirconium-organic framework [Zr6O4(OH)4(bpbodc)6]n (H2bpbodc = 4,7-bis(4-carboxypyrazol-1-yl)-2,1,3-benzoxadiazole) featured a luminescence “turn on” response to aliphatic amines making it promising for the fabrication of materials for detection of spoiled seafood.
