Abstract

Over a 0-7 T range, transient absorption microscopy on anthradithiophene organic crystals shows that singlet to triplet pair state conversion is anticorrelated with fluorescence yield. This shows how the dominant singlet fission charge multiplication pathway can be switched-off with increasing B-field or by changing the molecular packing motifs.
