合成了1-萘基-、9-菲基-和9-蒽基-取代的三烷基二硅烯1-3，作为第一个稳定的具有单个多环芳香取代基的二硅烯，允许阐明前所未有的二硅烯π和芳香π系统之间的分子内电荷转移相互作用。具有低位pi*（芳基）LUMO的蒽基取代的二硅烯3由于从二硅烯pi供体到芳族pi受体的电荷转移而显示出明显的ICT吸收带。
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 pi and aromatic pi systems. Anthryl-substituted disilene 3 having a low-lying pi*(aryl) LUMO showed a distinct ICT absorption band due to the charge transfer from a disilene pi donor to an aromatic pi acceptor.
