The Impact of Chirality on Singlet Fission and Triplet Fusion: A Molecular Twist for Photon Management

Chirality has recently emerged as a new means to profoundly impact the properties of organic semiconductors for spin-optoelectronic applications. Yet, a clear mechanistic understanding of chiral structure–property relationships remains absent to date, particularly for photon interconversion processes such as singlet exciton fission and triplet fusion. In this perspective, we highlight recent work that investigates chiral structures for these processes. We discuss the various ways in which chirality can impact such conversion processes and suggest ways to leverage it to improve photon management for both energy applications and quantum information science.
