• Novel Photophysical Properties of Gold Selenide Complexes:  Photogeneration of Singlet Oxygen by [Au₁₈Se₈(dppe)₆]Br₂ and Near-Infrared Photoluminescence of [Au₁₀Se₄(dpppe)₄]Br₂

  The photoluminescence (PL) properties of several recently synthesized ligand-stabilized polynuclear gold(I) selenide complexes were investigated. [Au18Se8(dppe)(6)]Br-2 dppe = bis(diphenylphosphanyl) ethane}, (I) is distinguished by the bright-red long-lived PL (phosphorescence) in the solid state, photosensitization of singlet oxygen, O-1(2), in solution, and high photostability. The quantum yield of PL, phi(PL), is (7.5 +/- 0.5) x 10(-2) for the polycrystalline I at 293 K (determined using an integrating sphere) and increases up to similar to0.8 at 77 K. The quantum yield Of O-1(2) is 0.17 +/- 0.02 in O-2-saturated dichloromethane solutions. [Au10Se4(dpppe)(4)]Br-2 dpppe = bis(diphenylphosphanyl)pentane} (II) shows a broad near-infrared PL at 880 nm in dichloromethane [(phi(PL), = (4 1) x 10(-3)], which is shifted up to similar to1020 nm in the solid II at 77 K (psi(PL) similar to 3 x 10(-3)). Although the quantum efficiency of II as a luminophor is quite moderate, it is comparable to that of organic infrared laser dyes such as Styryl-20 and IR26. A particular configuration of the Au10Se4 core appears to be crucial for the near-infrared PL: the "isomeric" complexes [Au10Se4(dppm)(4)]Br-2 dppm = bis(diphenylphosphanyl) methane} (III) and [Au10Se4(depe)(4)]Cl-2 depe = bis(diethylphosphanyl) ethane} (IV) show no significant PL.

• Steric effects and aurophilic interactions in crystals of Au2(μ-1,2-bis(diphenylphosphino)ethane)X2 and Au2(μ-1,2-bis(dicyclohexylphosphino)ethane)X2 (X = Cl, Br, I)

  Crystals in the isostructural series Au-2(mu-dppe)X-2 (dppe is 1,2-bis(diphenylphosphino)ethane, X = CI, Br, I) form centrosymmetric, dimeric structures with two short Au center dot center dot center dot Au contacts between the component molecules. We found no evidence for a second polymorph for any member of the Au-2(mu-dppe)X-2 series, although two polymorphs were observed previously for the related Au-2(Ph2As(CH2)(2)AsPh2)X-2 series. Crystals of Au-2(mu-dcpe)X-2 (where dcpe is 1,2-bis(dicyclohexylphosphino)ethane) show structures that differ appreciably from those of Au-2(mu-dppe)X-2. The bulky cyclohexyl substituents appear to be playing a major role in eliminating the formation of polymeric or dimeric structures. Au-2(mu-dcpe)Cl-2 has a monomeric structure without aurophilic interactions. In contrast, Au-2(mu-dcpe)Br-2 and Au-2(mu-dcpe)I-2 have similar structures with intramolecular aurophilic interactions. Au-2(mu-dcpe)I-2 displays a form of aggregation-induced emission. It displays a red-pink luminescence in crystalline form but is non-emissive in solution. (C) 2016 Elsevier Ltd. All rights reserved.
