Study of the effect of the phosphane bridging chain nature on the structural and photophysical properties of a series of gold(I) ethynylpyridine complexes
Abstract
<p>Alkynyl Au<sup>I</sup> complexes of the type [Au(C≡CC <sub>5</sub>H<sub>4</sub>N)(PPh<sub>3</sub>)] (1) [Au<sub>2</sub>(C≡ CC<sub>5</sub>H<sub>4</sub>N)<sub>2</sub> (diphosphane)] [diphosphane = bis(diphenylphosphanyl)methane (2), bis(diphenylphosphanyl)isopropane] (3), bis(diphenylphosphanyl)acetylene (4), 1,2-bis(diphenylphosphanyl)ethane (5), 1,3-bis(diphenylphosphanyl)propane (6), 1,4-bis(diphenylphosphanyl)butane (7), 1,1′-bis(diphenylphosphanyl)ferrocene (8) and [Au<sub>3</sub>(C≡ CC<sub>5</sub>H<sub>4</sub>N)<sub>3</sub>(triphos)] [triphos = 1,1,1-tris(diphenylphosphanylmethyl)ethane] (9) were prepared by reaction of [Au(C≡CC<sub>5</sub>H<sub>4</sub>N)]<sub>n</sub> with the suitable phosphane. Determination of the X-ray crystal structures of several compounds bearing different carbon backbones between the phosphorus atoms reveals the influence of the nature of the phosphane spacer on the establishment of intra and/or intermolecular gold-gold interactions. The absorption and emission properties of the complexes were analysed by taking into account the presence or absence of intermetallic interactions. Although UV/Vis spectra show differences for compounds with intramolecular Au-Au contacts, a conclusive trend was not observed in the emission behaviour.</p>
