Title: A new carboxyl-copper-organic framework and its excellent selective absorbability for proteins

Abstract

One-pot solvothermal treatments of CuCl{sub 2}·2H{sub 2}O, H{sub 2}L (5-(3-methyl-5-(pyridin-4-yl)-4H-1,2,4-triazol-4-yl) isophthalic acid) and Sm(NO{sub 3}){sub 3}·6H{sub 2}O in water yielded a rare carboxyl-copper-organic framework, [Cu(HL)]{sub n}·nH{sub 2}O (1). The existence of carboxyl groups in compound 1 may be due to the interference of Sm(NO{sub 3}){sub 3}·6H{sub 2}O at the relatively high temperature and autogenous pressure of the reaction. Compound 1 has been characterized by single-crystal X-ray diffraction, PXRD, IR, and elemental analysis. Compound 1 is a 3D coordination polymer, and an xfe-4-Fddd, (4{sup 2}.6.8{sup 3}) topology in 1 is created. In addition, the optical properties have been investigated. Rhodamine B dyeing experiments exhibited that there were residual carboxyl groups on the surface of compound 1. UV–vis results showed that more lysozyme was adsorbed onto the surface of compound 1 than BSA at pH 7.4. At the same time, XPS spectra were also investigated to verify the results. - Graphical abstract: One-pot solvothermal treatments of CuCl{sub 2}·2H{sub 2}O, H2L (5-(3-methyl-5-(pyridin-4-yl)-4H-1, 2, 4-triazol-4-yl) isophthalic acid) and Sm(NO{sub 3}){sub 3}·6H{sub 2}O in water yielded a rare carboxyl-copper-organic framework, [Cu(HL)]n·nH{sub 2}O (1).
