Synthesis, characterisation and fluorescence property of a new one-dimensional polymer constructed from 5-nitroisophthalic acid

摘要: AbstractA new metal-organic coordination polymer [Zn(5-nip)(2,2′-bipy)]·1·5H2O (1) (5-nip = 5-nitroisophthalic acid; 2,2′-bipy 2,2′-bipyridine) was synthesised by using hydrothermal reaction of 5-nip, Zn(NO3)2·6H2O as well 2,2′-bipy. Combined with the characterisation elemental analysis, infrared spectrum, thermogravimetric analysis and X-ray single crystal diffractometer, it shows that complex exhibits an infinite one-dimensional zigzag chain constructed repeated units [Zn(5-nip)(2,2′-bipy)]·1·5H2O. In each units, metal Zn(II) centre coordinated 5-nip ligands five-coordinated number. While link to generate a chain. addition, 1 extends two-dimensional supramolecular architecture through π–π stacking hydrogen bonds. The fluorescence at ambient temperature.
