Applicability
of phototherapeutic CO-releasing molecules (photoCORMs)
is limited because they are activated by harmful and poorly tissue-penetrating
near-ultraviolet light. Here, a strategy is demonstrated to activate
classical photoCORM Mn2(CO)10 using red light
(635 nm). By mixing in solution a triplet photosensitizer (PS) with the photoCORM and shining red light, energy transfer occurs
from triplet excited-state 3PS* to a photolabile
triplet state of Mn2(CO)10, which, like under
near-UV irradiation, led to complete release of carbonyls. Crucially,
such “triplet-sensitized CO-release” occurred in solid-state
materials: when PS and Mn2(CO)10 were embedded in electrospun nonwoven fabrics, CO was liberated
upon irradiation with low-intensity red light (≤36 mW 635 nm).
