A stereogenic twisted cycloparaphenylene that glows with helical green light in a polymer matrix is depicted in the cover image. The helical array of cycloparaphenylene in the molecular structure provides remarkable circularly polarized luminescence (CPL) in the solid state. In particular, bright and remarkable CPL was observed in the polymethyl methacrylate (PMMA) film. This shining molecule dispersed in PMMA is like a lone but striking luminescent creature in a vast ocean. More information can be found in the Full Paper by M. Hasegawa, Y. Imai, Y. Mazaki, et al. on page 1323.

前封面：溶液和固态中固定手性联萘的立体弯曲对苯撑的圆偏振发光（Chem。Eur。J. 4/2021）

封面图像中描绘了一种立体异构的扭曲的环对亚苯基，它在聚合物基质中以螺旋绿光发光。分子结构中的环对亚苯基的螺旋排列在固态下提供了出色的圆偏振发光（CPL）。尤其是，在聚甲基丙烯酸甲酯（PMMA）膜中观察到了明亮而引人注目的CPL。散布在PMMA中的这种闪亮分子就像是茫茫大海中孤独而引人注目的发光生物。更多信息，请参见长谷川M.今井Y. Mazaki等人的论文全文。在第1323页。
