Abstract

Iridium complexation was investigated for β-tetraisopropyldinaphthoporphycene. Usage of 1,5-cyclooctadiene and dimethylformamide separately as solvents led to the formation of a Ir(I) complex with 1,5-cyclooctadiene (COD) as a secondary ligand and an additional complex where COD is oxidized. These are the first examples of complexes of porphycene or its isomers, where in-core iridium is stabilized in a 1+ oxidation state without any carbonyl ligands. The latter complex was found to be stable under aerobic conditions at elevated temperature. The synthesis, characterization, and photophysical and electrochemical properties of the Ir(I) complexes are elaborated on here.

卟啉稳定单金属Ir(I)配合物的β，β′-双吡咯融合

研究了铱与β-四异丙基二萘卟啉的络合作用。分别使用1,5-环二烯和二甲基甲酰胺作为溶剂，形成了以1,5-环二烯（COD）为二级配体的Ir(I)配合物和COD被氧化的附加配合物。这是卟啉或其异构体的第一个配合物的例子，在核心中铱稳定在1+氧化态，没有任何羰基配体。后一种复合物在高温下的有氧条件下是稳定的。本文阐述了Ir(I)配合物的合成、表征及其光物理和电化学性能。
