  • Exciton–exciton annihilation is conventionally assumed to be limited by diffusion. Now, using time-resolved photoluminescence microscopy to determine exciton diffusion constants and annihilation rates in two substituted perylene diimide aggregates, along with a microscopic model, it has been shown that annihilation can be suppressed through quantum interference of the spatial phase of delocalized excitons.

  • A complete understanding of singlet fission (SF) in molecular materials will enable the design of optimised optoelectronic devices. Here, the authors use vacancy control in acene-based blends to link coherent and incoherent SF pathways to energetics.

  • Here the authors induce asymmetric transmission in planar Fabry–Pérot microcavities by embedding organic thin films exhibiting apparent circular dichroism (ACD), an optical phenomenon based on 2D chirality.

  • The implications of coherence signals for the transfer of energy within the Fenna–Matthews–Olson complex of photosynthetic green sulfur bacteria is a well debated topic. Now, polarization-controlled 2D spectroscopy — aided by vibronic exciton modelling — has enabled the characterization of all such coherences and determination of their physical origins; while electronic coherences dephase extremely rapidly, ground- and excited-state vibrational coherences dominate.

  • 2D electronic spectroscopy found experimental indications of coherently interacting excitons and trions in doped transition metal dichalcogenides (TMDCs). Here, the authors perform simulations of 2D spectra of monolayer TMDCs based on a many-body formalism, allowing to relate exciton-trion coherence to quantum beats based on microscopic principles.

  • The observation of long-lived coherent oscillations in the nonlinear spectra of photosynthetic proteins has raised significant discussion on the role of quantum effects in biology. Using a model system, the signatures of inter-exciton coherence have been isolated, which has allowed the influence of vibronic coupling to be studied in unprecedented detail.
