Oxasmaragdyrin (a tiger‐paw‐shaped molecule) , a 22‐π electron aromatic macrocycle containing four pyrroles and a furan ring connected through three methine bridges and two direct bonds, is shown to be an excellent electron donor and photosensitizer. Donor–acceptor dyads involving BODIPYs have been synthesized and the occurrence of ultrafast photoinduced electron transfer leading to charge‐separated states is demonstrated using femtosecond transient spectroscopy. More information can be found in the Full Paper by F. D'Souza, M. Ravikanth et al. on page 1546 ff.
