Three new carbazole-based hole-transporting materials PTCz-9’Cz, PTCz-3’TCz, and PTCz-NTol2 were synthesized, characterized, and examined the propensity of exciplex formation with electron-transporting material PO-T2T. Through enhancing the electron-donating ability of the...
Two orange-red iridium complexes with high quantum yields and good electron mobility were applied in efficient OLEDs showing a maximum luminance of 129 466 cd m−2, a maximum current efficiency of 62.96 cd A−1 with low efficiency roll-off.
A highly efficient one-pot procedure for the synthesis of complexes of the type [Ir(COD)(Phox)]X, where Phox is a (chiral) phosphinooxazoline ligand, X = PF6 or B[(3,5-(CF3)2C6H3)]4 (BARF), is developed. Former reported syntheses demanded the isolation of pure ligands by column chromatography, but the ligands tend to adsorb irreversibly on silica. Moreover, the chromatography has to be performed with careful exclusion of air. The present method avoids this difficulties. The yields of the syntheses are comparable with those starting from the pure ligands. The method is also suitable for the preparation of complexes of the type [Rh(COD)(Phox)]BARF and [Rh(Phox)2]BARF.
Two new phenylpyridine derivatives-based heteroleptic iridium complexes, (Fppy)2Ir(dipg) (Fppdg) and (CF3ppy)2Ir(dipg) (tFmppdg) with emission peaks of 545 nm and 581 nm respectively, were designed and synthesized by incorporation of a...
