The Cover Feature shows novel gallium(III)‐ethynyl corroles, which serve as a precursor for Sonogashira cross‐coupling reaction with aryliodides in a flow‐reactor system. Theoretical and photophysical studies reveal that the optical properties of such gallium(III)‐ethinylcorroles can be selectively tuned with different aryl‐substituents. As an example, the novel gallium(III)‐pyridine‐5,10,15‐pyrenylethynyl‐corrole complex exhibits a Soret‐band maximum at 510 nm and emission maximum at 740 nm with fluorescence quantum yields ΦF = 0.27 in aerated toluene solution.
