Giving the green light : The connection of two Cr III sensitizers around a central Er III acceptor in a self‐assembled cation provides high local metal concentrations that favor efficient nonlinear energy transfer upconversion luminescence (see picture). Upon selective low‐energy near‐infrared irradiation of Cr III ‐centered transitions, 1 displays an unprecedented molecular two‐photon upconverted green Er III ‐centered emission.
