| Metal-organic frameworks built from aromatic carboxylate have attracted considerableattention in recent years because of their interesting molecular topologiesalong with potential applications in many areas including optical,electric and magnetic.Many papers on this work have already been reported.Here we use trans -cinnamonic acid with conjugate system as main ligand ,and obtain several complexes withfluorescent property.The main research results are described as follows:(1) Three acetate salt(Cd2+, Mn2+,Co2+) as precursors to react withtrans-cinnamonic acid(Hhca),three novel coordination compounds Cd(hca)2·2H2O,Mn(hca)2·2H2O,Co(hca)2·2H2O were obtained;After adding another ligand 1,10-phen,three new compounds Cu(hca)2(phen),Cd(hca) (phen)3,Zn(hca)2(phen),were obtained.All of the compounds were characterized IR,EA etc,furthermore thermal stability andfluorescent properties were investigated.(2) P-3-(4-Hydroxy-phenyl) -acrylic acid was obtained unexpected utilizing Hhcaas precursor under hydrothermal treatment.The structure was characterized byH-NMR,IR,EA,ESMS etc.Fluorescent property was also studied.Because of themulti-carboxy groups cotaining in,we tried to absorb nocuous metal ions,and find it hasescellent absorbtion with Pb2+,Cd2+.(3) Three 5-Amino-4H- [1,2,4] triazole-3-thiol ramifications have been studied.Utilize it as precursor,try to synthesize complexes with Pb2+,Cu2+,thenfluorescentproperty of products was studied.
