Effective Negative Diffusion of Singlet Excitons in Organic Semiconductors

[Image: see text] Using diffraction-limited ultrafast imaging techniques, we investigate the propagation of singlet and triplet excitons in single-crystal tetracene. Instead of an expected broadening, the distribution of singlet excitons narrows on a nanosecond time scale after photoexcitation. This...
