摘要：

The compound fac-Ir(ppy)(3) (fac, facial; ppy, 2-phenylpyridyl) end-functionalized poly(4-diphenylaminostyrene) (PDAS) was synthesized by adding fac-Ir(ppy)(2)(vppy) (vppy, 2-(4-vinylphenyl)pyridyl) to poly(4-diphenylaminostyryl) lithium (PDASLi). In this reaction, fac-Ir(ppy)(2)(vppy) acts as a fac-Ir(ppy)(3) single-monomer addition reagent for PDASLi. The first fac-Ir(ppy)(2)(vppy) molecule readily binds to the carbanion of PDASLi, but the addition of a second fac-Ir(ppy)(2)(vppy) molecule to the carbanion on the vinyl group of fac-Ir(ppy)(2)(vppy) does not proceed. Thus, fac-Ir(ppy)(3) end-functionalized PDAS, which consists of one PDAS molecule and one fac-Ir(ppy)(3) molecule, was successfully obtained for the first time.
