l two new phosphorescent cationic iridium(III) cyclometalated diimine complexes are coordinated by cyclometalated ligands consisting of hole-transporting diphenylamino(DPA)-and fluorene-

l l These robust iridium complexes can be

thermally vacuum-sublimed and used as phosphorescent dyes for the fabrication of high-efficiency organic light-emitting diodes (OLEDs).

These devices doped with 5 wt% can produce efficient electrophosphorescence with a maximum brightness of up to 15 610 cdm–2and a peak external quantum efficiency of ca. 7% photons per electron that corresponds to a

The difference in the ligation position results in significant shifts in the emission spectra with the changes in wavelength being 84 nm for the Ir complexes and 63 nm for the Pt complexes. The electrochemical behavior and photophysical properties of the complexes are investigated and correlate well with the results of density functional theory (DFT) calculations. Electroluminescent devices with a configuration of

l l Extension of the p-conjugation through incorporation of electronpushing

carbazole units to the fluorene fragment leads to bathochromic shifts in the emission profile, increases the highest occupied molecular orbital levels and improves the charge balance in the resulting complexes because of the propensity of the carbazole unit to facilitate hole transport.

These iridium-based triplet emitters give a strong orange phosphorescence light
