Previously limited to highly symmetrical homoleptic triple‐helical complexes [Er(Lk)3]3+, where Lk are polyaromatic tridentate ligands, single‐center molecular‐based upconversion using linear optics and exploiting the excited‐state absorption mechanism (ESA) greatly benefits from the design of stabl...
