  摘要：

  Utilization of Sonogashira coupling reactions with cis-[Pt(dppe)Cl-2] and varying amounts of the alkynyl ligands HC=CRC=CH (where R = p-C6H4, p-C6H4-p-C6H4) afford the monoplatinum complexes cis[Pt(dppe)(C=CRC=CH)(2)] (R = p-C6H4 (1a), p-C6H4-p-C6H4 (1b)), the diplatinum complexes cis[(HC=CRC=C)Pt(dppe)(C=CRC=C)Pt(dppe)(C=CRC CH)] (R p-C6H4 (2a), p-C6H4-p-C6H4 (2b)), the triplatinum complexes cis- [(HC=CRC=C)Pt(dppe)-(C=CRC=C)Pt(dppe)(C=CRC=C)Pt(dppe)-(C=CRC=CH)] (R = p-C6H4 (3a), p-C6H4-p-C6H4 (3b)), and the respective oligomeric species 4a,b, all in reasonable yields. X-ray diffraction studies of 2a reveal the presence of two independent diplatinum molecules in the asymmetric unit, each with C-i symmetry. All the complexes have been fully characterized by NMR and mass spectrometry, and GPC analysis of 4a,b indicate their oligomeric nature, with a degree of polymerization of ca. 4. Electronic spectral studies indicate that the optical band gap decreases with increasing chain length but that the intensity of the triplet state emission increases with the number of repeating units. As expected, there is less effective pi-conjugation along the chain in the cis configuration as compared to the analogous trans-oriented species.
