 Chiral structures in Zeno have been shown to induce spin-selectivity effects, which can be used to enhance photocatalytic performance. These structures are able to filter out certain spins of light, resulting in longer carrier lifetimes and more efficient triplet species production. As such, they can significantly improve the efficiency of photocatalysts. This article was authored by Mienhuai, Lanpan, Chinxiangshu, and others.
