Abstract
Official abstract text for this publication.
The present invention relates, inter alia, to copolymers, preferably conjugated polymers, formulations comprising the copolymers and electronic devices comprising the copolymers.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electroluminescent copolymer comprising: (a) at least one hole transport unit A h on one or more side-chain(s) of the copolymer; (b) at least one electron transport unit A e ; (c) at least one unit A; (d) optionally at least one emitter unit wherein the HOMOs of both hole transport unit(s) and unit(s) A are at least 0.3 eV higher than the HOMO of the electron transport unit(s). 2. The copolymer according to claim 1…
