Abstract

The preparation of the 3, 6-disubstituted dibenzosilole monomers 4, 5 and 10 by two different routes is described; Suzuki copolymerisation afforded poly (9, 9-dioctyl-3, 6- dibenzosilole) 11 which has a sufficiently high triplet energy (2.55 eV) to function as a host for green electrophosphorescent emitters.
