  para-Ethynyl aniline as a building block for fully π-conjugated ligands and acetylide complexes: crystal structures of trans-[Pt(PPh3)2(CCC6H4NH2)2] and [(μ-H)Ru3(CO)9(μ3-CCC6H4NH2)]

  摘要：

  para-Ethynyl aniline has been prepared, structurally characterised and investigated as a building block towards fully pi -conjugated multifunctional ligands and complexes. Palladium-copper catalysed coupling with aryl halides affords a number of new amino-substituted aryl acetylenes, while using [Ni(CO)(2)(PPh3)(2)] as a catalyst, cyclotrimerisation and dimerisation to give an ene-yne were competitive. Reaction of para-ethynyl aniline with low-valent metal centres affords acetylide complexes trans[Pt(PR3)(2)(C=CC6H4NH2)(2)] (R = Ph, Bu-n), cis-[Pt(eta (2)-dppe)(C=CC6H4NH2)(2)], all trans-[Ru(CO)(2)(PEt3)(2)(C=CC6H4NH2)(2)] and [(muH)Ru-3(CO)(9)(mu C-3=CC6H4NH2)]. The bis(acetylide) trans-[Pt(PPh3)(2)(C=CC6H4NH2)(2)] has been used to prepare extended chain complexes with amide, imine, imino-phosphorane and ferrocenyl imine units being generated. Attempts to prepare polymers via reaction with terephthaloyl chloride lead only to the formation of oligomers with an average of four monomer units. (C) 2000 Elsevier Science B.V.

  Spectroscopic and Phosphorescent Modulation in Triphosphine-Supported PtAg₂Heterotrinuclear Alkynyl Complexes

  摘要：

  A series of highly phosphorescent PtAg2 heterotrinuclear alkynyl complexes with bis(diphenylphosphinomethyl)-phenylphosphine (dpmp) were prepared and characterized structurally. The solution phosphorescence with various emitting colors is systematically modulated by modifying substituents as well as pi-conjugated systems in aromatic acetylides. The crystals, powders, or films exhibit reversible stimuli-responsive phosphorescence changes upon exposure to vapor of MeCN, pyridine, DMF, etc., resulting from perturbation of d(8)-d(10) metallophilic interaction in the excited states as a consequence of the formation/disruption of Ag-solvent bonds. Both experimental and time-dependent density functional theory (TD-DFT) studies demonstrate that d(8)-d(10) metallophilic interaction exerts a crucial role on phosphorescent characteristics due to the PtAg2 cluster-based (3)[d -> p] state. This study affords a paradigm for phosphorescence modulation in d(8)-d(10) heteronuclear complexes.
