Diphenyldisilane derivative having electron-donating and -withdrawing groups in each phenyl group, 1-(4-cyanophenyl)-2-(4-methoxyphenyl)-1,1,2,2-tetramethyldisilane was synthesized, and its excited-state property was studied. Intramolecular charge-transfer character through the disilanyl group was confirmed; the dipole moment of the excited-state has been estimated to be 28 debye.
