Abstract
The electronic device of the invention comprises one or more active elements, each comprising a first and a second electrode and an active layer of organic material separating the first and second electrodes. Examples of active elements are thin-film transistors and light-emitting diodes. The active layer comprises a polymeric material having conjugated units A and non-conjugated intermediate units B, which intermediate units B separate the conjugated units A from each other, such that no conjugation extends from a first conjugated unit Ato a second conjugated unit A. The polymeric material may be a polymer network, an alternating copolymer or a polymer in which the conjugated units are present in side chains. The polymer can be prepared from monomers having a B-A-Bstructure, wherein at least one of Band Bcomprises a reactive group enabling polymerization.
