中文摘要:
      为寻找更好的苯基吡唑类席夫碱衍生物的发光材料,以苯基吡唑为结构母体设计合成了6种苯基吡唑缩单胺类席夫碱系列衍生物.通过IR, 1H NMR, MS和元素分析等对这6种目标产物进行了表征,其中1-(2,6-二氯-4-三氟甲基-苯基)-5-[(2-羟基亚苄基)-氨基]-1H-吡唑-3-甲腈,即APY(PhOH)的结构进一步通过单晶衍射确证,并测试了其紫外、荧光光谱,探讨了其电化学性质和光物理性能.结果表明:6种苯基吡唑缩单胺类席夫碱衍生物的结构与设计相符,具有有效的共轭结构与发光效能,是良好的发光材料,为设计合成具有优良发光性能的共轭型有机发光材料奠定基础.
英文摘要:
      In order to develop better luminescent materials of phenyl pyrazole Schiff base derivatives, six derivatives of phenyl pyrazole monoamine Schiff base were synthesized by using phenyl pyrazole as start material. All the derivatives were characterized by IR, 1H NMR, MS and element analysis and the structure of 1-(2,6-Dichloro-4-trifluoromethyl-phenyl)-5-[(2-hydroxy-benzylidene)-amino]-1H-pyrazole-3-carbonitrile, namely APY (PhOH) was further confirmed by single crystal diffraction. Its UV and fluorescence spectra were also studied to explore the electrochemical and photophysical properties. The result showed that the structures of the six derivatives of phenyl pyrazole monoamine Schiff base were consistent with the design and had efficient conjugated structure and luminous efficiency, which would lay the foundation for the design and synthesis of conjugated organic luminescent materials with excellent luminous efficiency.
