The Cover Feature illustrates the chlorosomal J ‐aggregate of an ethynylene and p ‐phenylene inserted chlorophyll‐ a derivative. The rigid linear linker is useful for the control of hydroxy orientation to allow the J ‐aggregation in spite of the extended chlorin‐to‐chlorin distance. Their optical properties (including the drawn spectra) were measured and discussed with an equation shown in the background. More information can be found in the Article by T. Nakano and H. Tamiaki on page 338 in Issue 5, 2020 (DOI: 10.1002/cptc.202000012).
