A series of luminescent cyclometalated platinum(II) complexes, (C^N^N)Pt(C≡CR) [HC^N^N=4 (4 tolyl) 6 phenyl 2,2′ bipyridine; R=4 chlorophenyl (1), phenyl (2) and 4 tolyl (3)], were synthesized, and their spectroscopic properties have been examined. These complexes are brightly emissive both in fluid solution and in the solid state, attributed to triplet metal to ligand charge transfer ( 3MLCT) state. The excited state energy can be tuned by ancillary acetylide ligands. The emission lifetimes in dichloro^methane solution at room temperature were up to 1 64 μs and the emission quantum yields were in the range of 0 03-0 15.

Four metallated conjugated oligothiophenes, S-1, S-2, S-3 and S-4, with platinum（II） aryleneethynylenes as the electron-rich building block were synthesized to investigate their physicochemical and photovoltaic properties. These small molecules possess fairly low-lying HOMO energy levels which match with the LUMO energy level of the electron acceptor PC70BM （[6,6]-phenyl-C71-butyric acid methyl ester）. Using the simple process of spin-coating solution fabrication technique, S-I：PC70BM （1：4, w/w） based organic solar cells exhibiting a high Voc of 0.913 V, with a PCE value of 0.88% were developed. In contrast, the OSC device based on S-2：PC70BM （3：7, w/w） displayed a higher PCE of 1.59% with a higher Jsc value of 5.89 mA cm^-2. The device based on S-4：PCToBM （1：4, w/w） exhibited a PCE value of 1.56%, with a Voc of 0.917 V.

Two silver(I) complexes were prepared by the reaction of [Ag(C≡CPh)]n with NP3 [NP3 = N(CH2CH2PPh2)3] or with NP3 and [Cu(CH3CN)4]ClO4. Complex 1 [(Ag2Cl(NP3)2)(Ag5- (C≡CPh)6)] contains both NP3 and PhC≡C- ligands. The complex cation is (Ag2Cl(NP3)2)+, in which two Ag(NP3)+ cations were bridged by a Cl- donor. The anion is (Ag5(C≡CPh)6)-, where five Ag+ ions are linked by six C≡CPh- to form a pentanuclear cluster. Complex 2 only contains NP3 ligand, where the silver center adopts a trigonal-bipyramidal geometry. Crystal data for 1: C133H116Ag7Cl3- N2P6, Mr = 2789.54, triclinic, space group P1, a = 13.0780(2), b = 15.3678(2), c = 31.2041(3) ?, α = 91.3928(7), β = 90.9328(8), γ = 96.0244(4)o, V = 6233.8(1) ?3, T = 293(2) K, Z = 2, Dc = 1.486 g/cm3, F(000) = 2796, μ = 1.266 mm-1, the final R = 0.0746 and wR = 0.1953 for 16475 observed reflections with I > 2σ(I).

Soluble platinum（Ⅱ） polyyne polymers trans-{Pt-[P（C4H8N）3]2（C≡C）2R（C≡C）2-}n and trans-{Pt-[P（C4H3O）3]2（C ≡C）2R（C ≡ C）2- }n （R = 9,9-dihexylfluorene-2,7-diyl） have been prepared in good yields by CuI-catalyzed polymerization involving the dehydrohalogenating coupling of trans-{PtCl2[P（C4H8N）3]2} and trans-{PtC12[P （C4H3O）312} with H（C≡C）2R（C≡C）2H, respectively. We report the optical spectroscopy of these polyplatinaynes. The influence of the heavy metal atom in these metal alkynyl systems on the intersystem crossing rate and the spatial extent of lowest singlet and triplet excitons was systematically characterized. Our investigations indicate that the organic triplet emissions can be harvested by the heavy-atom effect which enables efficient intersystem crossing from the S1 singlet excited state to the T1 triplet excited state.
