Summary:The Front Cover shows the crystal packings of a zwitterionic triarylmethylium salt and Japanese maple leaves. The zwitterion was easily synthesized by one‐pot and two‐step reactions from potassium 4‐bromophenyltris(pentafluorophenyl)borate and exhibits vivid color change in the solid state from green to yellow and then to red by dissolution/evaporation and grinding, respectively. In addition, single crystals of the zwitterionic salts with green, yellow, and red colors could be obtained with different crystal systems, and thus the crystal packings are highlighted with the corresponding colors. Japanese maple leaves turn from green to red, heralding the arrival of autumn. The cover design also reflects a wish for the arrival of the harvest season in chemical research.
