Abstract
A polymer, a mixture containing the same, a formulation, an organic electronic component, and a monomer for polymerization. The polymer comprises a repeat unit E1 and a repeat unit E2. An E1 group on a side chain of the repeat unit E1 and an E2 group on a side chain of the repeat unit E2 have features for forming Exciplexes, min((LUMO(E1)−HOMO(E2), LUMO(E2)−HOMO(E1))≤min(ET(E1),ET(E2))+0.1 eV being satisfied, and accordingly a polymer suitable for printing technologies is provided, thereby reducing manufacturing costs of OLEDs.
