Iron photosensitizers represent a holy grail in photochemistry, but their widespread implementation is limited by short excited-state lifetimes and poor cage escape yields. Here, the introduction of an anthracene moiety appended to iron(III) complex allowed solve both limitations generate novel dyad exhibiting extraordinary lifetime 11.5 μs. The key achieving this remarkably long depopulation short-lived iron-centered emissive excited state populate dark triplet located on anthracene-like with spin-forbidden deactivation. Population only occurs ∼10% efficiency acetonitrile still allows expansion scope reactivity accessible iron-based photosensitizers, which now encompasses energy transfer 3O2. In addition, proof-of-principle investigation methyl viologen as electron acceptor, population drastic ten-fold increase yield from 4.5% for unsubstituted 42% molecular dyad. Hence, new provides complementary approach complexes based first-row transition metals alternatives well-established analogues precious metals. We believe that further spectroscopic investigations synthetic modifications acceptor linkage photosensitizer will be use these innovative dyads applications near future.

Light energy conversion often relies on photosensitizers with long-lived excited states, which are mostly made of precious metals such as ruthenium or iridium. Photoactive complexes based highly abundant iron seem attractive for sustainable conversion, but this remains very challenging due to the short state lifetimes current complexes. This study shows that a luminescent Fe(III) complex sensitizes triplet-triplet annihilation upconversion anthracene derivatives via underexplored doublet-triplet transfer, is assisted by preassociation between photosensitizer and annihilator. In presence an organic mediator, green-to-blue efficiency Φ
