Outside Back Cover: Artificial Decision Tree Guided Screening of Ultralong Room‐Temperature Phosphorescent Cocrystals with Locally Excited States (Angew. Chem. Int. Ed. 51/2025)

In the Research Article (e202521837) by Dongpeng Yan and co-workers, a workflow for constructing locally excited triplet states in charge transfer cocrystals is proposed and a universal descriptor developed. According to this descriptor, various room temperature phosphorescent cocrystals can be synthesized, and the longest room temperature phosphorescence lifetime of cocrystals can reach 1.223 s. These type of cocrystals can be applied to information encryption and time resolution optical logic gates.
