The Front Cover illustrates three benzocoumarin (benzo[f], [g], and [h] coumarin)-fused triskelion-shaped dyes derived from a parent coumarin-fused triskelion and their crystal packing. The different positions of the benzo group on the [f], [g], and [h] sites of coumarin give the triskelion-shaped coumarin platform unique helices, twists, thicknesses, and planarities. This modification also affects the molecular assemblies, the molecular inversion processes, and the emission properties. More information can be found in the Research Article by M. Ueda, Y. Mazaki, and co-workers (DOI: 10.1002/ejoc.202400015).

封面展示了三种苯并香豆素（苯并[f]、[g]和[h]香豆素）稠合三臂形染料，其衍生自母体香豆素稠合三臂结构及其晶体堆积。苯并基团在香豆素的[f]、[g]和[h]位点上的不同位置赋予三腿形香豆素平台独特的螺旋、扭曲、厚度和平面性。这种修饰还会影响分子组装、分子反转过程和发射特性。更多信息请参阅 M. Ueda、Y. Mazaki 及其同事的研究文章 (DOI: 10.1002/ejoc.202400015)。
