Ou, Ya-Ping published the artcileSynthesis, Characterization, and Properties of Anthracene-Bridged Bimetallic Ruthenium Vinyl Complexes [RuCl(CO)(PMe3)3]2(μ-CH:CH-anthracene-CH:CH), Name: 9,10-Diethynylanthracene, the publication is Organometallics (2011), 30(21), 5763-5770, database is CAplus.
Four anthracene-based bimetallic Ru vinyl complexes, in which two Ru units are attached at different positions (the 9,10-, 1,5-, 2,6-, and 1,8-positions) of the anthracene moiety, were synthesized by treating the appropriate anthracene-based ethynes with [RuHCl(CO)(PPh3)3]. These bimetallic complexes were thoroughly characterized by NMR, x-ray diffraction, and elemental anal. According to the single-crystal x-ray structures, the 2,6-disubstituted Ru vinyl complex has a more planar structure compared with the 9,10-disubstituted complex, possibly because it has less steric hindrance. Also, the optical electronic properties of these complexes were studied, such as their UV/visible absorption spectra, fluorescence spectra, and electrochem. properties. The optical electronic results indicated that the 2,6-disubstituted Ru vinyl complex displayed the strongest fluorescence emission due to the more planar structure of its organic conjugated bridge, and the electrochem. studies showed that the two Ru centers displayed obvious differences in electronic communication when they are located at different positions on the anthracene unit, with the 9,10- and 1,8-disubstituted Ru vinyl complexes exhibiting better electronic communication and higher stability of the mixed-valence complex than the 1,5- and 2,6-disubstituted complexes.
