摘要：

A coordination polymer, [Pb(L-F)Cl](n) (compound 1), based on Pb(II) cations and 5-fluoronicotinic acid was successfully synthesized under the solvothermal synthesis condition. The resultant two-dimensional sample has been characterized by physicochemical and spectroscopic methods, including element analysis, powder X-ray diffraction, luminescent spectra, UV-Vis spectra, thermogravimetric analysis, as well as single-crystal X-ray diffraction analysis. The counter anion Cl- from PbCl2 can take part in the assemble process of compound 1. The result sample exhibited that the framework of compound 1 can be affected by the counter anions. Compound 1 is considered as a luminescent sensor for nitroaromatic compounds with the excellent recyclability. The detection limit and K-SV value of the as-synthesized sample to PA are 1.41 x 10(-5) mot L-1 and 1.39 x 10(4)M(-1). In addition, it is able to be served as a solid luminescent sensor for the temperature. (C) 2019 Elsevier B.V. All rights reserved.
