Abstract:
A fluorene-based copolymer of formula I includes a monomeric unit that includes a fluorene group and at least one steric hindering chemical group to provide sufficient steric interaction such that the spatial conformation of the fluorene-based copolymer is substantially non-planar. The fluorene-based copolymer exhibits UV light emission.
