Two- and three-photon absorption and excitation phosphorescence of oligofluorene-substituted Ir(ppy)3.

چکیده
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 × 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.

متن کاملTuning the emission of cyclometalated iridium complexes by simple ligand modification
The photo-excitation and relaxation of a new cyclometalated complex, Ir(ppy)2fppy, is investigated through the measurement of absorption and photoluminescence spectra. Comparison of Ir(ppy)2fppy with Ir(ppy)3 reveals that the lowest energy excited state of Ir(ppy)2fppy is localised on the aldehyde-substituted ligand, thus giving the complex its characteristic orange emission (lmax # 600 nm). OL...
متن کاملA cyclometalated iridium(III) complex with enhanced phosphorescence emission in the solid state (EPESS): synthesis, characterization and its application in bioimaging.
Iridium(III) complexes with intense phosphorescence in solution have been widely applied in organic light-emitting diodes, chemosensors and bioimaging. However, little attention has been paid to iridium(III) complexes showing weak phosphorescence in solution and enhanced phosphorescence emission in the solid state (EPESS). In the present study, two β-diketonate ligands with different degrees of...

متن کاملTheoretical study on the electron transfer and phosphorescent properties of iridium(III) complexes with 2-phenylpyridyl and 8-hydroxyquinolate ligands.
The complexes AlQ(3) and Ir(ppy)(3) (Q = 8-hydroxyquinolate; ppy = 2-phenylpyridyl) are typical green emitting fluorescence and phosphorescence materials, respectively. Here we hybridize Ir(ppy)(3) with AlQ(3) to investigate the optoelectronic properties of the Ir(III)-centred derivatives including (ppy)(2)IrQ, (ppy)IrQ(2) and IrQ(3) by using density functional methods. Our calculations show th...
