摘要: Abstract Four luminescent metal-organic complexes based on semi-rigid N-donor ligands and 3-hydroxy-2-naphthoic acid (3-HNA), [Zn(bimb)(3-HNA)2] (1), [Zn(bbimb)(3-HNA)2]·3H2O (2), [Zn(bimbp)(3-HNA)2] (3), [Cd(bimbp)(3-HNA)2] (4) [bimb = 1,4-bis(1-imidazol-yl-methyl)benzene, bimbp = 4,4′-bis(1H-imidazol-1-yl-methyl)biphenyl, bbimb = 1,4-bis(1-benzimidazolyl-yl-methyl)benzene], have been synthesized solvothermally. The 1D chain structures of 1–4 exhibit the Z-type or linear geometry configurations, where combination transition metal ions is regarded as backbones, 3-HNA are dangled covalently both sides such backbone. investigation luminescence properties indicates that detection capabilities against Fe3+ Cr2O72− in DMF with excellent selectivity sensitivity.
