The Cover Feature shows dipyridylpolyene molecules with different numbers of double bonds, and the constellation Orion. The monoene (bpe) and the diene are strongly fluorescent in the solid state because of the aggregation‐induced emission effect, whereas the triene and the longer polyenes are only weakly fluorescent. The two highly emissive molecules are located at the positions of the two brightest stars, Rigel and Betelgeuse, in the constellation. More information can be found in the Full Paper by Y. Sonoda and co‐workers (DOI: 10.1002/cplu.202000285).

封面文章：一系列α，ω-二（4-吡啶基）多烯的晶体结构和荧光光谱性质：聚集诱导发射的影响（ChemPlusChem 9/2020）

封面特征显示具有不同双键数目的二吡啶基多烯分子和星座猎户座。由于聚集诱导的发射效应，单烯（bpe）和二烯在固态下具有强荧光性，而三烯和较长的多烯则仅具有弱荧光性。这两个高发射分子位于星座中两个最亮的恒星Rigel和Betelgeuse的位置。可以在Y. Sonoda及其同事的论文全文中找到更多信息（DOI：10.1002 / cplu.202000285）。
