摘要:

以方胺功能化配体5,5′-[(3,4-二氧环丁-1-烯-1,2-二基)二(氮烷二基)]二间苯二甲酸(H4L)和六水合硝酸钴为原料, 在碱性条件下通过水热反应制备了一种方胺功能化的金属-有机框架材料(Co-L). X射线单晶衍射结果显示, 该材料是由一维链通过CH…π和氢键相互作用形成的三维网络结构, 在b轴和c轴方向分别存在窗口直径为0.52和0.63 nm的一维孔道. 荧光测试结果表明, Co-L可在20种天然氨基酸中高选择性地检测组氨酸, 并对其检测机理进行了研究.

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
