Abstract

Abstract : Light‐Stimulated Luminescence Switching In article number 2205046 by Daisuke Kosumi, Tuyoshi Fukaminato, Tetsuya Kida, and co‐workers, lead halide perovskite nanocrystals (NCs) are coupled with photochromic diarylethene (DAE) molecules to control the photoluminescence (PL) emission from the NCs by light stimulation. Stable PL switching is achieved by the addition of 2, 2, 6, 6‐tetramethylpiperidine‐1‐oxyl (TEMPO), which captures the residual holes generated via electron transfer from the NCs to the closed‐ring isomer of DAE.
