Abstract

Silyl groups affect photochemical properties of aromatic compounds. When aromatic compounds are substituted by silyl groups, the UV absorption bands show a bathochromic shift and the extinction coefficients of the absorption maxima increase. Theoretical calculations show that these electronic effects of silyl groups are explained by the cooperation of sigma-pi conjugation in the HOMO and sigma*-pi* conjugation of the LUMO.
