	abstract = {A series of triscyclometalated iridium complexes with oligofluorene-substituted ppy ligands manifest impressive two-and three-photon absorption properties. In particular, a star-shaped complex bearing three carbazole-terminated trifluorenyl ppy demonstrates a large three-photon absorption cross section up to 81 x 10(-78) cm(6) s(2) photon(-2). In combination with optimal phosphorescence quantum yields (0.5-0.8), such iridium complexes are effective two-and three-photon excited phosphorescence emitters.},
