Surface-initiated
polymerization of poly(9,9-dioctylfluorene)
(PFO), an important blue light-emitting polymer, was
performed from
microparticles. The grafting process is based on Kumada
catalyst-transfer polycondensation and lead to PFO brushes of a high grafting
density. The high grafting density is a reason of unusually strong propensity of the tethered PFO chains to
adopt planar and ordered conformations (b-phase). Our method should be extendable for the preparation of various
micro- and nanosized objects having conjugated polymer shells with precisely
preorganized chains and thus it would become a powerful tool in engineering of
new materials for optoelectronic application.
