Chirality in the photochemical mer→fac geometrical isomerization of tris(1-phenylpyrazolato, N, C2′)iridium(III)

Irradiation of the optically resolved mer-Δ isomer of tris(1-phenylpyrazolato,N,C2′)iridium(III) with 366-nm light in CH3CN purged by argon at 25 °C gave 59 % fac-Δ and 41 % fac-λ (18%ee) at the end of geometrical isomerization. Form

METHOD FOR PRODUCING CYCLOMETALATED IRIDIUM COMPLEX

The present invention provides a method for producing a cyclometalated iridium complex by use of a non-chlorine iridium raw material. The method for producing a cyclometalated iridium complex includes producing a cyclometalated iridium complex by reacting a raw material including an iridium compound with an aromatic heterocyclic bidentate ligand capable of forming an iridium-carbon bond, the raw material being non-halogenated iridium having a conjugated base of a strong acid as a ligand. Here, the non-halogenated iridium is preferably one containing a conjugated base of a strong acid having a pKa of 3 or less as a ligand.

A Synthesis and Luminescence Study of Ir(ppz)3 for Organic Light-Emitting Devices

Tris(1-phenyl-κC1-pyrazolato-κN2)iridium (Ir(ppz)3) was prepared and its luminescence properties were investigated for the application to organic light-emitting devices (OLEDs). The photoluminescence (PL) spectra of Ir(ppz)3 in dichloromethane showed a peak at 437 nm at room temperature. The luminescent lifetime of an Ir(ppz)3 film doped in CBP was found to be 218 ns, which indicated that its emission is phosphorescent. OLEDs were fabricated with doped films of Ir(ppz)3 in several hosts, and the electroluminescence (EL) peak was observed at 450 nm. The luminance of OLEDs was pure blue, with the CIE coordinates of x = 0.158, y = 0.139 at 100 cd/m2, but luminous efficiencies were low since the LUMO of Ir(ppz)3 is higher than those of the hosts used.
