Twisted oxygen-containing oligosilanes—unprecedented examples of σ–n mixed conjugated systems
Literature Information
Clemens Krempner, Ralf Ludwig, Anke Flemming, Ralf Miethchen, Martin Köckerling
Twisting the silicon backbone conformation in oxygen containing oligosilanes towards dihedral angles of 120–130° either by intramolecular hydrogen bonding or incorporation into a covalently bonded ring system effectively extends the delocalization of electrons in these σ–n mixed conjugated systems.
