A new ligand 2-（4,5-dihydro-2-thiazolyl）-6-methoxyl benzothiazole and its new dinuclear Co（II） coordination complex [Co（C11H10N2OS2）Cl2]2·2CHCl3 （1） have been synthesized and characterized. Complex 1 was synthesized by the reaction of Co（II） salt with 2-（4,5-dihydro- 2-thiazolyl）-6-methoxyl benzothiazole under room-temperature evaporation condition and struc- turally characterized by single-crystal X-ray diffraction analysis and IR spectroscopy. The supramolecular network of complex 1 is stabilized by the presence of intermolecular interaction, such as C-H···Cl hydrogen bonding and π-π stacking. The complex crystallizes in triclinic, space group P1 with a = 8.3288（12）, b = 10.5273（15）, c = 10.822（2）, α = 93.416（3）, β = 90.864（3）, γ = 94.890（3）o, V = 943.60（2）3, Z = 2, Dc = 1.758 g/cm3, F（000） = 498 and μ = 1.840 mm-1. The final complex [Co（C11H10N2OS2）Cl2]2·2CHCl3 is a diplex bridged dinuclear complex consisting of two Co（II） ions, two ligands, two bridging Cl- anions and two terminal Cl- anions.
A series of novel and convenient fluorescent probes with Schiff base functionality were presented for direct detection of OCI via the irreversible OCl-promoted oxidation and hydrolyzation reaction in formation of the ring-opened product, fluorescein. Prominent high sensitivity, selectivity and antiinterference OCl-induced fluorescence and color change over a wide range of tested metal ions performance were observed for each probe under physiological conditions, thus making the probes well suitable for sensing of OCl in living cells.
