摘要：

Glow in the dark: A tunable singlet-triplet exchange gap arises in optically active conjugated polymers that exhibit both strong fluorescence from the singlet state and pronounced phosphorescence from triplet excitations (see picture). The polymers were incorporated into organic light-emitting diodes (OLEDs). © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
