New Arylene–Germylene–Vinylene Compounds: Stereoselective Synthesis, Characterization, and Photophysical Properties

The stereoselective route toward new molecular and macromolecular compounds containing arylene–germylene–vinylene units is described. The reagents for germylative coupling reaction were 1,4-bis(dimethylvinylgermyl)benzene (1) and vinyl- and divinylarenes with ruthenium complexes (2a, 2b) as catalysts. NMR characterization of all isolated products, results of MS and elemental analysis for molecular compounds (3–5), and GPC for oligomers (6–8) are presented. Absorption and luminescence properties of the synthesized compounds are discussed and compared with those of model chromophores.
