中文摘要:
      以2,4-二氟苯硼酸、4,4'-二溴-2,2'-联吡啶为原料合成了4,4'-二(2,4-二氟苯基)-2,2'-联吡啶,并以此为N^N配体合成新型离子型环金属钌配合物。采用元素分析、红外光谱、1H-NMR以及质谱表征确认了产物的结构,并考察了其光物理性能。结果表明,联吡啶4,4'-位上取代基团的引入改变了配合物的MLCT态,使其最大发射波长(λmax)较经典配合物Ru(bpy)32+(λmax=590 nm)红移至613 nm;配合物的初始分解温度为356℃,具有较好的热稳定性。
英文摘要:
      A new cyclometalated ruthenium complex was synthesized from 2,4-difluorobenzeneboronic acid, 4,4'-dibromo-2,2'-bipyridine and cis-bis-(2,2'-bipyridine)dichlororuthenium(II) dehydrate. The complex was characterized by element analysis, IR spectra, 1H-NMR and mass spectrometry. Its UV-Vis absorption and photoluminescence was measured. The data showed that an introduction of the 2,4-difluoro-phenyl substituent into the 4,4'-site of 2,2'-bipyridine would alter metal-to-ligand charge transfer (MLCT) transition, leading to a significant red shift of the photoluminescence spectra (λmax) from 590 to 613 nm. The cyclometalated ruthenium complex, as evidenced by TG measurements, has good thermo- stability and the decomposition temperature is up to 356℃.
