Photochemical hole burning (PHB) of free‐base porphyrins in host polymers as a site‐selective spectroscopy reveals the existence of vibronic structure in a porphyrin Q‐band peak and low‐energy excitation modes of host polymers. A new mechanism of photon‐gated PHB by two‐color sensitization of photoreactive polymers with a zinc porphyrin is also presented.
