1-Naphthyl-, 9-phenanthryl-, and 9-anthryl-substituted trialkyldisilenes 1-3 were synthesized as the first stable disilenes with single polycyclic aromatic substituents, allowing elucidation of the unprecedented intramolecular charge transfer interaction between disilene π and aromatic π systems. Anthryl-substituted disilene 3 having a low-lying π*LUMO showed a distinct ICT absorption band due to the charge transfer from a disilene π donor to an aromatic π acceptor.
