Siloxane−Triarylamine Hybrids: Discrete Room Temperature Liquid Triarylamines via the Piers−Rubinsztajn Reaction

A series of room temperature liquid siloxane−triarylamine hybrids were synthesized using the Piers−Rubinsztajn reaction. These materials displayed well behaved electrochemical oxidation and low T g’s and were free-flowing liquids. The interaction between the Lewis acidic tris(pentafluorophenyl)boran...

Zusammenfassung:A series of room temperature liquid siloxane−triarylamine hybrids were synthesized using the Piers−Rubinsztajn reaction. These materials displayed well behaved electrochemical oxidation and low T g’s and were free-flowing liquids. The interaction between the Lewis acidic tris(pentafluorophenyl)borane catalyst and the Lewis basic starting triarylamine substrate was also investigated by steady state UV−vis spectroscopy and 19F NMR.
