Abstract
Summary: A monoterpyridine‐poly(ethylene glycol) (mono‐tpy‐PEG) and a novel monoterpyridine‐PEG‐functionalized iridium(III) complex were successfully synthesized and fully characterized by means of NMR, IR, and UV‐vis spectroscopy, as well as gel permeation chromatography and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry. The functionalized monoterpyridine iridium(III) complex was synthesized by a bridge‐splitting reaction of a dimeric iridium(III) precursor complex using a chelating terpyridine ligand with a poly(ethylene glycol) tail. With this approach, a new class of light‐emitting polymeric materials revealing interesting optical properties was made avaialable. Upon excitation of a spin‐coated film of the iridium(III) complex prepared here, a yellow emission color (two bands in figure) was observed. image Upon excitation of a spin‐coated film of the iridium(III) complex prepared here, a yellow emission color (two bands in figure) was observed.Keywords
