Contributors: H. Kee*, C. Kirmaier *, Q. Tang *, J. Diers*, C. Muthiah n, M. Taniguchi n , J. Laha n, M. Ptaszek n ...

topics (OpenAlex): Porphyrin and Phthalocyanine Chemistry; Photosynthetic Processes and Mechanisms; Photochemistry and Electron Transfer Studies
TL;DR: The spectral, vibrational and excited‐state decay characteristics are examined for a set of synthetic chlorins and the zinc chlorins with the red‐most fluorescence also have the greatest radiative decay rate constant and are expected to have the fastest nonradiative internal conversion to the ground state.
