The cover picture shows 1,4,7,10‐tetraisoalkyltetracenes in the solid state under UV light irradiation and under natural light. The photophysical properties exhibit crystallochromy ranging from yellow to red and different fluorescence quantum yields depending on the length of the alkyl side chain. The isopropyl derivative achieved the highest quantum yield ever reported among tetracenes. Details are discussed in the article by C. Kitamura et al. on p. 3033 ff. The background of the cover picture is a night view of Himeji Castle, which is well known for its beauty and supposed resemblance to an egret (it was accorded UNESCO World Heritage Site status in 1993). The authors would like to thank Hiroko Kitamura for her help in designing the cover picture.
