• Incorporation of 2,2,3,3,5,5,6,6,7,7,8,8-dodecamethyl-2,3,5,6,7,8-hexasilabicyclo[2.2.2]octan-1-yl moiety into such chromophores as biphenyl, terphenyl, stilbene, and tolan was found to induce bathochromic shifts of absorption and fluorescence spectra, compared with those of the parent chromophores. Moreover, enhancement of the molar extinction coefficients and the fluorescence quantum yields by the substitution was also observed. These results indicate that σ–π conjugation between the polysilacage moiety and the chromophores is operative. Theoretical study of the polysilacage-substituted chromophores is also presented.
