Abstract

Dual singlet–triplet fluorescence–phosphorescence emitting compounds demonstrate that plasmonic surface enhancement is controlled solely by the underlying oscillator strength of a transition: metal-free compounds with weak spin–orbit coupling show no enhancement in phosphorescence efficiency even though fluorescence is amplified.
