Absorption and fluorescenceproperties of silyl‐substituted stilbenes were investigated. The derivative in which four Me3Si groups were introduced at the ortho positions did not fluoresce at room temperature. The para bis‐Me3SiC≡C‐substituted analog has a high fluorescence quantum yield (0.95). The stilbene containing Ph2N and Me3SiC≡C groups exhibited solvatofluorochromism while maintaining a good
