Circularly polarized electroluminescence from an achiral fluorophore induced by co-assembly with chiral polymers

In this paper, this chiral supramolecular co-assembly ( R/S -P2-Bpy ) can not only emit deep blue CPL (λ em = 420 nm, |g em | = 0.042) in spin-coated films, but also act as an EML of a CP-EL device (λ em = 418 nm, |g EL | = 0.021).
