Solid state structures and photophysical properties of (trimethylsilyl)methyl-substituted anthracenes and pyrenes

摘要

(Trimethylsilyl)methyl groups incorporated at 9- and 9,10-posi-tions of anthracenes and at 1,3,6,8-positions of pyrenes were found to orient perpendicular to the aromatic frameworks in their crystals and induce red-shift of UV absorption and fluorescence
