Abstract
A polymer comprising a repeat unit of formula (I): (I) wherein each Ar1 and each Ar2 independently represents a substituted or unsubstituted aromatic or heteroaromatic group; each Cy independently represents a saturated heterocyclic or carbocyclic ring that may be unsubstituted or substituted with one or more substituents; n is 1, 2 or 3; and adjacent groups Ar2 may be linked by a divalent linking group in the case where n is 2 or 3. The polymer may be used as a charge-transporting material or light-emitting material in an organic light-emitting device.
