Page/Page column 4, (2013/09/12)
Monodentate gold ethynyl complexes having a gold-carbon bond and a gold-phosphorous bond, specifically, of formula I, may be useful in optoelectric devices, wherein Ar1 and Ar2 are independently monocyclic or polycyclic aryl, unsubstituted or substituted with one or more alkyl, alkenyl, alkoxy, aryl, aryloxy, fluoro, fluoroalkyl, or perfluoroalkyl; and R is substituted or unsubstituted aryl.

The compounds (E)-4-XC≡CC6H4CH=CHPh [X=SiMe3 (1), H (2)], 1,3,5-{(E)-4-XC6H 4CH=CH}3C6H3 [X=I (3), C≡CSiMe3 (4), C≡CH (5)], [Au{(E)-4-C≡CC 6H4CH=CHPh}(L)] [L=PPh3 (6), PMe3 (7)], [Au(4-C≡CC6H4C≡CPh)(L)] [L=PPh 3 (8), PMe3 (9)], 1,3,5-[(Ph3P)Au{(E)-4- C≡CC6H4CH=CH}]3C6H 3 (10), trans-[Ru{(E)-4-C=CHC6H4CH=CHPh} Cl(dppm)2]PF6 (11), trans-[Ru{(E)-4-C≡CC 6H4CH=CHPh}Cl(L2)2] [L 2=dppm (12), dppe (13)], [1,3,5-(trans-[(dppm)2ClRu{(E)-4- C=CHC6H4CH=CH}])3C6H 3](PF6)3 (14), 1,3,5-(trans-[(L 2)2ClRu{(E)-4-C≡CC6H4CH=CH}]) 3C6H3 [L2=dppm (15), dppe (16)] and 1,3,5-(trans-[(dppe)2(PhC≡C)Ru{(E)-4-C≡CC 6H4CH=CH}])3C6H3 (17) have been prepared (and the identity of 6 confirmed by a single-crystal X-ray diffraction study), and their electrochemical (Ru complexes) and nonlinear optical (NLO) properties assessed. The ruthenium complexes display reversible (12, 13, 15-17) or nonreversible (11, 14) processes attributable to Ru-centered oxidation, at potentials similar to those of previously-investigated monoruthenium alkynyl or vinylidene complexes. No evidence for intermetallic electronic communication in 14-17 is observed. Quadratic nonlinearities at 1064 and 800 nm for the octopolar stilbenyl-ruthenium complexes 14, 15 are large for compounds without strongly accepting substituents. Cubic molecular hyperpolarizabilities at 800 nm for the organic compounds and gold complexes are low. Cubic nonlinearities |γ|800 and two-photon absorption (TPA) cross-sections σ2 for the ruthenium complexes increase on proceeding from linear analogues 12, 13 to octopolar complexes 15, 16; the latter and 17 possess some of the largest |γ|800 and σ2 values for organometallics thus far. Cubic nonlinearities Im(χ(3))/N for 13, 16, and 17 from the first application of electroabsorption (EA) spectroscopy to organometallics are also large, scaling with the number of metal atoms.
