中文摘要:
      以1,10-邻菲罗啉为辅助配体,设计合成了三个二苯氨基修饰的阳离子型环金属铂(II)配合物Ⅰ-Ⅲ。系统研究了配合物的光物理、电化学及氧传感性能。结果表明,在2-(4-二苯氨基)苯基吡啶的吡啶环的5位引入不同基团,可实现铂(II)配合物的发光波长在544 nm - 583 nm之间调控。其中,在吡啶环的5位引入三氟甲基的配合物Ⅲ的最大发射波长为583 nm。氧传感性能测试结果表明,在吡啶环的5位引入三氟甲基的配合物Ⅲ的氧敏感性能显著提升,其在DMF溶液中的I0/I2.17值为6.4。
英文摘要:
      Three diphenylamino modified cationic cyclometalated platinum(II) complexes Ⅰ-Ⅲ have been designed and synthesized with 1,10-phenanthroline as an auxiliary ligand. The photophysical, electro-chemical and oxygen sensing properties of the complexes were investigated systematically. The results show that the introduction of different groups at the 5-position of the pyridine ring of 2-(4-diphenylamino) phenylpyridine can tune the emission wavelength of the platinum(II) complexes from 544 nm to 583 nm. The maximum emission wavelength of the trifluoromethyl-substituted complex Ⅲ is 583 nm. The results of oxygen sensing tests show that the oxygen sensitivity of the complex Ⅲ is remarkably improved, with a value of I0/I2.17 up to 6.4 in DMF.
