Various silicon-containing six-membered-ring molecules were synthesized by Pd-catalyzed coupling reaction of 1,2-bis(dimethylsilyl)arenes with 1,2-diiodoarenes in moderate yields. Their optical properties were investigated via UV-vis absorption, fluorescence and phosphorescence spectroscopies, which indicated that the σ?-π?conjugated system expanded owing to the silicon atoms. Some of the compounds exhibited enhanced luminescence, larger Stokes shift, and phosphorescence in comparison with 9,9,10,10-tetramethyl-9,10-dihydroanthracene. Density functional theory (DFT) studies were also performed to investigate the photophysical properties of the compounds.

The countercation effect on the reactivity of ambiphilic o-(fluorodimethylsilyl)phenyl anion was investigated by replacing Li in 1 with Cu (4 and 5), Mg (6), and Zn (7). The reactivity of the aryl metal species was estimated by the yields of dimerized pro

Bis[o-(hydrosilyl)phenyl]cuprates and bis[o-(fluorosilyl)phenyl]cuprates were prepared by reacting [o-(hydrosilyl)phenyl]lithiums and [o-(fluorosilyl)phenyl]lithiums, respectively, with copper salts, such as CuCN and Cu(OPiv)2. The phenylcuprat
