摘要

前封面说明了稳定性的改善以及热激活延迟荧光（TADF）特性，如寿命和效率，通过修改有机发射器的核心获得。TADF染料的性能得到了增强，从9,9-二甲基芴到更大的9,9 ' -螺芴。在薄膜和晶体两种染料中都检测到非常长的延迟荧光，其中庞大的核心是减少失活分子间途径的关键。更多信息可以在Fabio Rizzo及其同事的研究文章中找到（DOI: 10.1002/cptc.202400235）。

Front Cover: Fluorene vs. Spirobifluorene: Effect of the π-System on TADF Properties (ChemPhotoChem 12/2024)

The Front Cover illustrates the improvement on stability as well as on thermally activated delayed fluorescence (TADF) characteristics, such as lifetime and efficiency, obtained by modifying the core of the organic emitters. The properties of TADF dyes are enhanced going from 9,9-dimethyl-fluorene to the more bulky 9,9’-spirobifluorene. Very long delayed fluorescence has been detected in both dyes as thin films and crystals, where the bulky core is pivotal to reduce deactivating intermolecular pathways. More information can be found in the Research Article by Fabio Rizzo and co-workers (DOI: 10.1002/cptc.202400235).
