Back Cover: Highly Luminescent One‐Dimensional Organic–Inorganic Hybrid Double‐Perovskite‐Inspired Materials for Single‐Component Warm White‐Light‐Emitting Diodes (Angew. Chem. Int. Ed. 2/2023)

Double perovskites are one of the most promising candidates for developing white-light-emitting diodes owing to their intrinsic broadband emission from self-trapped excitons. In their Research Article (e202213240), Feng Liu, Bin Yang, and co-workers report a novel highly luminescent one-dimensional double-perovskite-inspired material with a warm-white photoluminescence quantum yield of 92 %. Furthermore, single-component warm-white light emitting diodes were fabricated by using this material.
