Carbazole-Substituted Iridium Complex As A Solid State Emitter For Two-Photon Intravital Imaging

A tris-cyclometalated iridium complex that beats two ligands functionalized by peripheral carbazole groups combines an intense solid state emission and a significant two photon absorption cross section in the near-infrared. After incorporation into a physiological micellar suspension, it can be used for the intravital two-photon fluorescence microscopy of cerebral vasculature.
