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
