Abstract

The n(Si)→3p(Si) absorption maxima of silylenes were shifted significantly red by introducing trimethylsilyl and trimethylgermyl substituents. The origin of the substituent effects will be attributed to the σ-electron donating ability of the trimethylmetal groups which lift the energy level of n(Si) orbital significantly.
