Reversible spin-optical interface in luminescent organic radicals.

ABSTRACT: Molecules present a versatile platform for quantum information science^1,2 and are candidates for sensing and computation applications^3,4. Robust spin-optical interfaces are key to harnessing the quantum resources of materials⁵. To date, carbon-based candidates have been non-luminescent^6,7, which prevents optical readout via emission. Here we report organic molecules showing both efficient luminescence and near-unity generation yield of excited states with spin multiplicity S > 1. This was achieved by designing an energy resonance between emissive doublet and triplet levels, here on covalently coupled tris(2,4,6-trichlorophenyl) methyl-carbazole radicals and anthracene. We observed that the doublet photoexcitation delocalized onto the linked acene
