| 摘要: 通过AgCl、PPh3和MBT以1:2:1的物质的量之比反应得到2种不同的配合物[AgCl(PPh3)2(BTZT)]·CH3OH (1)和[AgCl(PPh3)2 (BTZT)]2 (2)(PPh3=三苯基膦;MBT=2-巯基苯并噻唑;BTZT=苯并噻唑-2-硫酮)(其中2已报道)。配合物[AgBr(PPh3)2(BTZT)]·CH3OH (3)和[AgBr(PPh3)2(BTZT)]2 (4)改用AgBr以相似的反应获得(其中2已报道)。通过红外光谱、元素分析、核磁共振氢谱、X射线单晶衍射、荧光光谱对配合物1和3进行了分析和表征。我们发现在不同的化学环境中,MBT配体可以转化为BTZT配体,原因是其具有化学活性基团。荧光光谱表明1和3的发射峰均源于配体中的π-π*跃迁。 |

| Abstract: Two kinds of complexes [AgCl(PPh3)2(BTZT)]·CH3OH (1) and [AgCl(PPh3)2(BTZT)]2 (2) were obtained by the reaction of AgCl, PPh3, and MBT in 1:2:1 molar ratio (PPh3=triphenylphosphine; MBT=2-mercaptobenzo-thiazole BTZT=benzothiazoline-2-thione) (2 has been reported). [AgBr(PPh3)2(BTZT)]·CH3OH (3) and [AgBr(PPh3)2(BTZT)]2 (4) were prepared in a manner similar to 1 and 2 using AgBr (4 has been reported). Complexes 1 and 3 have been characterized by IR, elemental analysis, 1H NMR spectroscopy, fluorescence spectrum and single-crystal X-ray diffraction. The MBT ligand can transform into the BTZT ligand in different chemical environment because of its chemically active groups. The luminescent spectra show that emission peaks of 1 and 3 are assigned to the ligand centered π-π* transition. |
