Organic Long‐Persistent Luminescence: Many Exciplex Systems Exhibit Organic Long‐Persistent Luminescence (Adv. Funct. Mater. 22/2020)

In article number 2000795, Ryota Kabe, Chihaya Adachi, and co-workers show that many exciplex systems exhibit afterglow emission because of the charge separation event during photoexcitation. The emission pathway and color of organic long-persistent luminescence can be controlled by the relationship between the local excited states and charge-transfer excited states of materials.
