Abstract

A three-layered poly(benzyl ether) dendrimer having a bis-ethynylbenzene core was synthesized and characterized with ¹H NMR and MALDI-TOF-MS spectroscopy. The dendrimer was reacted with platinum complexes to obtain platinum-acetylide based organometallic polymers. When the dendrimer was reacted with trans-[PtCl₂(PEt₃)₂], a high molecular weight polymeric compound was formed, whereas, with cis-[PtCl₂dppp], a uniform molecular weight compound was formed, which was found to be a dimeric metallacycle by ¹H NMR, ³¹P NMR and ESI-TOF-MS spectroscopy. Both these complexes exhibited relatively a strong emission around 440 nm, indicating that they could be potential candidates for blue emitting polymer LEDs.
