Abstract

A three-layered poly(benzyl ether) dendrimer having a bis-ethynylbenzene core was synthesized and characterized with $^{1}H$ 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-[$PtCl_{2}(PEt_{3})_{2}$], a high molecular weight polymeric compound was formed, whereas, with cis-[$PtCl_{2}dppp$], a uniform molecular weight compound was formed, which was found to be a dimeric metallacycle by $^{1}H\;NMR,\;^{31}P\;NMR$ 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.
