The cover feature represents the photoexcitation of a N,N‐bis(phenylethyl)perylene diimide (PDI) chromophore to the singlet excited state using a femtosecond short laser pulse. The photoexcited chromophore forms a S₁S₀ dimer (in blue) together with a neighboring PDI chromophore. Singlet fission then occurs within one picosecond and with full efficiency that changes the S₁S₀ dimer state into the doubly excited triplet state T₁T₁ (in purple). This fission process is shown to be independent of morphology. Details are given in the Full Paper by F. C. Grozema and co‐workers on page 230 in Issue 4, 2018 (DOI: 10.1002/cplu.201700449).

封面人物：ylene二酰亚胺薄膜中形态学无关的高效单重态激子裂变（ChemPlusChem 4/2018）

覆盖特征表示使用飞秒短激光脉冲将N，N-双（苯乙基）per二酰亚胺（PDI）生色团光激发到单重激发态。光激发发色团与相邻的PDI发色团一起形成S ₁ S ₀二聚体（蓝色）。然后，单重态裂变在1皮秒内发生，并具有充分的效率，将S ₁ S ₀二聚体状态变为双激发三重态T ₁ T ₁（紫色）。已表明该裂变过程与形态无关。细节由F.C.Grozema及其同事在2018年第4期第230页的全文中给出（DOI：10.1002 / cplu.201700449）。
