Abstract

Upon photoexcitation, self-assembled PDI nanocrystals (S₁S₀) in the form of rods of 70 nm width and 1 μm length are subject to a symmetry breaking charge separation (SBCS) as the first step in the singlet fission (SF) sequence. Hereby, the correlated pair of triplet excited states ¹(T₁T₁) is formed with a quantum yield of 122%. Decoherence and triplet diffusion within the nanocrystals affords a long-lived, uncorrelated pair of triplet excited states (T₁ + T₁) with a quantum yield of 24%.
