Abstract
Pt-containing meta- and para-linked poly(phenyleneethynylene)s were synthesized by the dehydrochlorination coupling polymerization of PtCl2(PBu3)2 with m- and p-diethynylbenzenes. The formed polymers were sintered at 900 °C to obtain Pt-graphene hybrids, whose structures were examined by Raman scattering spectroscopy, X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) measurements. Shapes─facets, terraces, and steps─with average diameters of 2.0-3.4 μm were observed by field emission scanning electron microscopy (FE-SEM). The Pt-graphene hybrids moderately adsorbed CO2 and O2 and slightly adsorbed ethylene and methane. Epoxidation of stilbene was carried out using Pt-graphene hybrids as catalysts to obtain stilbene oxide.

Abstract
Platinum-containing macrocycles (platinacycles) have gained attention due to their unique photoelectric properties. In the present study, a novel conjugated platinacycle was synthesized by the dehydrochlorination coupling reaction of a bipyridine dichloroplatinum(II) complex and a 3,6-diethynylcarbazol derivative. The structure of the platinacycle was confirmed by 1H/13C, 1H-1H COSY, HMQC, HMBC, DEPT NMR spectroscopies in conjunction with DFT calculations, IR spectroscopy and MALDI-TOF mass spectrometry. The platinacycle exhibited a UV-vis absorption around 540 nm assignable to ligand-ligand charge transfer, and birefringence in DMF, possibly due to alignment of molecules.
