摘要
以2−(对甲苯基)吡啶为环金属主配体,4,4′−二叔丁基−2,2′−联吡啶为辅助配体,合成出了一种新型阳离子型铱配合物[Ir(mppy)2(dtbbpy)]PF_(6)(mppy=2−(对甲苯基)吡啶,dtbbpy=4,4′−二叔丁基−2,2′−联吡啶).其结构通过元素分析、核磁共振谱、质谱、红外光谱进行了表征,并测试了单晶结构.研究了其光物理性能,同时考察了它的热稳定性.结果表明,配合物为单斜晶系、P121/c1空间群;它在二氯甲烷溶液中为黄绿光发射,最大发射波长为566 nm.
A new cationic iridium(Ⅲ)complex:[Ir(mppy)2(dtbbpy)]PF_(6)(mppy=2−(4−methylphenyl)pyridine,dtbbpy=4,4′−ditert-butyl−2,2′−bipyridine)was successfully synthesized with pyridine compound as cyclometalated ligand and 4,4′−ditert-butyl−2,2′−bipyridine as auxiliary ligands.Its structure was characterized by elemental analysis,NMR(^(1)H and ^(13)C),MS and FT−IR,and the structure of single crystal was tested.Photophysical property of this complex and its thermal stability were investigated.The results show that the complexes were monoclinic crystal system and P121/c1 spatial group.A strong yellow-greenemission at 566 nm was observed in photoluminescence absorption spectra of the compound.
