We have designed and synthesized a new luminescent coordination polymer[Zn2(NO3)(NCP)3(H2O)3]n·2 nH2O(1,HNCP=2-(2-carboxyphenyl)imidazo-[4,5-f]-1,10-phenanthroline)under hydrothermal conditions,which has been structurally characterized by single-crystal X-ray diffraction analyses.1 crystallizes in monoclinic,space group P21/n,with a=13.7748(3),b=19.2651(4),c=19.9543(4)?,β=95.339(2)o,V=5272.35(19)?3,C60 H39.73 N13 O13.33 Zn2,Mr=1286.80,Dc=1.621 g/cm3,Z=4,μ(Mo Ka)=2.118,F(000)=2629,the final R=0.0598 and w R=0.1483.In 1,the organic ligand NCP-displays two different bridging modes to connect adjacent Zn(II)ions into a 1 D chain along the c-direction.Photoluminescent analyses reveal that 1 exhibits a strong green emission with a fluorescent lifetime of 5.57 ns.The first-principle calculation results show that the luminescence mainly originates from ligand-centered charge transition. 相似文献
