A process for end-capping a semi-conducting polymer

摘要

A process for end-capping a semi-conducting polymer, wherein said process comprises replacing the end group of at least one terminus of said polymer with an end-capping compound; and said end-capping compound is not charge transporting and comprises at least two rings. The polymer preferably comprises a plurality of monomers polymerized in the presence of a catalyst e.g. palladium catalyst. The end-capping group may comprise one or more fluorine groups. Also shown is a method of forming an end-capped polymer and a semi-conducting polymer. The polymer may be used in an electronic device e.g. a light emitting diode.
