摘要：

Three new ternary cobalt(s)-coordination polymers containing isomers of bis(benzimidazole) linkers, namely, (Co(TBTA)(L1)(2))(n) (1), (Co(TBTA)(L2)(2)](n) (2) and (Co(TBTA)(L3)(1.)(5)](n) (3) (L1 = 12-bis(benzimidazol-1- yirnethyl)benzene, L2 = 1,3-bis(benzimidazol-1-ylmethyl)benzene, L3 = 1,4-bis(benzimidazol-1ylmethyl)benzene, H(2)TBTA = tetrabromoterephthalic acid) were hydrothermally synthesized and characterized. 1 exhibits a 3D uninodal pcu framework, 2 possesses a hcb layer and 3 is a 1D chain structure. 1, 2 and 3 are highly sensitive and selective luminescent chemosensors for detection of acetylacetone, benzaldehyde and Cr2O72- anions in water.
