  摘要：

  The reaction of [PtCl2(cod)] with mesitylmagnesium bromide yields [PtBr(Mes)(cod)]. The compound crystallizes in the monoclinic space group P2(1)/c with a = 27.151 (5) angstrom, b = 7.987 (2) angstrom, c = 15.308 (2) angstrom, beta = 96.24 (2)degrees, V = 3300.2 (11) angstrom3, and Z = 8. Least-squares refinement converged at R = 0.0776 and R(w) = 0.0641 on the basis of 4049 reflections with F > 4.0sigma(F). The cyclooctadiene may be displaced by PPh3 or PEt3 to give the cis-bis(phosphine) complexes, which isomerize slowly to their trans forms. Carbonylation of trans-[PtBr(Mes)(PEt3)2] leads to the corresponding aroyl complex, but the PPh3 complex shows no tendency to undergo carbonyl insertion. Methylation of [PtBr(Mes)(cod)] yields the mixed organoplatinum complex [PtMe-(Mes)(cod)]. Treatment with HCl results in cleavage of the platinum-mesityl bond exclusively. Reaction of [PtClBz(cod)] with MeMgBr produces [PtMeBz(cod)]. Displacement of the diene from these mixed organoplatinum species by PPh3 or PEt3 generates the corresponding cis-bis(phosphine) compound.

  The Pt(bodipy)-(mercaptopyrene) dyad BPtSPyr shows four different emissions: intense near-infrared phosphorescence (Φph up to 15%) from a charge-transfer state pyrS˙+-Pt-BDP˙−, additional fluorescence and phosphorescence emissions from the 1ππ* and 3ππ* states of the bodipy ligand at r.t., and phosphorescence from the pyrene 3ππ* and the bodipy 3ππ* states in a glassy matrix at 77 K.

  将Pt（BODIPY） - （mercaptopyrene）DYAD BPtSPyr示出了四个不同的排放量：强的近红外磷光（Φ pH值最多至15％）从电荷传输状态pyrS˙ + -Pt-BDP - ，附加荧光和磷光发射从1 ππ*和3个在室温的BODIPY配体，并从芘磷光的ππ*状态3个ππ*和BODIPY 3个77 *ππ在玻璃状基质态K.
