An anthryl-substituted exocyclic silene, 3-silylene-2-silaaziridine, was synthesized by isomerization of the corresponding disilacyclopropanimine. The UV-vis spectrum of the silene shows a distinct intramolecular charge transfer (ICT) transition from the pi orbital of the Si=C double bond to the pi* orbital of the anthryl moiety. The relatively high-lying pi(Si=C) orbital of the 3-silylene-2-silaaziridine moiety and the low-lying pi* orbital of the anthryl group would be responsible for the distinct ICT band.
