Characterization And Photoluminescent Properties Of Coordination Polymer Materials Constructed By Organic Conjugated Carboxylic Acids

With the continually crossing and amalgamation of discipline, analytical chemistry plays an significant role in the research of subdiscipline of Chemistry, materials science, biological science and energy and environmental science; thereinto, the characterization of functional materials is one of the new growing points. The intense contemporary interest in the coordination polymer materials based on the d10 /lanthanide metal ions not only stems from their intriguing aesthetic structures and topological features, but most importantly derives from their potential extensive application prospects in the field of luminescence, electricity, magnetism, catalysis, fluorescence labeling and molecular recognition. In the paper, we firstly present the synthesis of three series of d10 /lanthanide coordination polymer materials (total 17 examples), which are constructed from the building units of H2ppdb (H2ppdb = [2,3-f]pyrazino[1,10]phenanthroline-2,3-dicer -boxylic acid), H2pht (H2pht = phthalic acid), H2ip (H2ip = isophthalic acid) and H2bdc (H2bdc = benzene dicarboxylic acid). Respectively, [H2ppdb](1), [Ag(Hppdb)(H2ppdb)] (2), [AgHppdb]n(3), {[Ag2(Hppdb)2(bpe)]·5.5H2O}n(4), {[Ln(ppdb)(Hppdb)(H2O)2]·2H2 O}n [Ln = Pr(5), Nd(6), Sm(7), Eu(8), Tb(9)], {[Pr2(ppdb)3(H2O)4]·2H2O}n(10), [Zn(pht) (bth)0.5(H2O)]n(11), [Cd(pht)(bth)0.5(H2O)]n(12), {[Cd2(ip)2(bte)(H2O)2]·2H2O}n(13), {[Zn(ip)(btp)(H2O)]·2H2O}n(14), {[Cd2(ip)2(btp)2(H2O)2]·5H2O}n(15), [Zn(ip)(bth)]n(16), [Cd(bdc)(bth)(H2O)2]n(17).These materials were characterized through X-ray single crystal diffraction analysis, elemental analysis, fourier transform infrared spectra technology, thermal analysis technology, luminescence measurement technology. Furthermore, we focus on the analysis and study of structural features, thermostability, fluorescence and near-infrared luminescent properties of aforementioned materials, and explore the structure-activity relationship between structure and properties, ultimately, obtain certain regularity conclusion.
