ACETYLENE BRIDGED LINKERS AND METAL-ORGANIC FRAMEWORKS (MOFS) PRODUCED THEREOF

The present invention relates to acetylene bridged linkers, metal-organic frameworks produced thereof, processes for producing the linkers and the MOFs and their use.

Acetylene Bridged Linkers and Metal-Organic Frameworks (MOFs) Produced Thereof

Described are acetylene bridged linkers, metal-organic frameworks produced thereof, processes for producing the linkers and the metal-organic frameworks, and the use of the metal-organic frameworks. The metal-organic frameworks possess an enhanced ability to adsorb and desorb high amounts of gases, in particular methane or hydrogen. The metal-organic frameworks have a high porosity and, thus, a high inner surface.

Highly sensitive salicylic fluorophore for visual detection of picomole amounts of Cu2+

Four new fluorophores containing multiple fluorogenic branches of phenylene-ethynylene and salicylic acid Cu2+ binding sites are synthesized and evaluated as Cu2+ sensors in aqueous media. The fluorophore, F4, having a triphenylamine core and three fluorogenic branches, possesses superior sensitivity, selectivity and emission properties for fluorescence quenching detection of Cu2+. This fluorophore exhibits the highest Cu2+ quenching sensitivity in aqueous solution; K sv = 5.79 × 106 M-1. The relatively high fluorescence emission of this fluorophore provides excellent visual contrast in a solid state paper-based sensor that enables naked eye detection of Cu 2+ at the picomole level.
