Abstract:

A novel squaramide-containing metal-organic framework(Co-L) has been prepared by solvothermal reaction of 5,5′-[(3,4-dioxocyclobut-1-ene-1,2-diyl)bis(azanediyl)]diisophthalic acid and cobalt nitrate hexahydrate in alkaline water. X-Ray single crystal diffraction result shows that Co-L is a three-dimensional framework structure formed by one-dimensional chains through hydrogen bonding and CH…π interaction and has 1D channels with the window diameters cross section of 0.52 and 0.63 nm along b and c directions, respectively. Fluorescence tests displayed that Co-L could detect histidine among 20 natural amino acids with high selectivity, and the detection mechanism was also studied.

Key words: Metal-organic framework, Histidine, Fluorescence recognition, Squaramide, Amino acid
