UV–visible absorption spectra of 6 and 7 were recorded
by using a Varian 5000 spectrophotometer. Photolumines-
cence (PL) spectra were measured with a He:Cd laser (k:
325 nm, and continuous wave) as the excitation light
source and a photomultiplier tube (PMT, Hamamatsu) with
a monochromator (Acton Research Co., SpectraPro 2300i)
as the detector. Cyclic voltammograms (CV) of the Ir(III)
complexes were recorded by using a Princeton Applied Re-
search (AMETEK VSP) potentiostat at room temperature on
0.1 M solutions of the Ir(III) complexes in acetonitrile or
dichloromethane containing tetrabutylammonium per-
chlorate (Bu4NClO4) at a scan rate of 100 mV/s under nitro-
gen gas. Pt was used as the working and counter electrode
and Ag/AgCl electrode as the reference electrode.

The PL efficiencies of doped films containing 6 and 7
were measured using the integrating sphere (Newport)
with a He:Cd laser (k: 325 nm, and continuous wave) as
the excitation light source. The absolute PL efficiency mea-
surement system was calibrated by using two standard
lamps of LS-1-CAL calibrated light source and DH-2000
deuterium–tungsten halogen light source (Ocean Optics,
Inc.). Transient photoluminescence of the phosphorescent
dye doped films were measured using a Nd:YAG laser (k:
355 nm, 10 Hz, and 9 ns pulse width) as the excitation light
source and PMT (Hamamatsu) with a monochromator
(Acton Research Co., SpectraPro 2300i) as the detector.
The samples were kept in a vacuum chamber maintained
at pressures under 10ꢁ3 Torr during the measurement.

The PhOLEDs were fabricated by using thermal evapora-
tion onto a cleaned glass substrate precoated with indium
tin oxide (ITO) under a vacuum. Prior to organic layer depo-
sition, the ITO substrates were exposed to UV-ozone flux for
10 min following degreasing in acetone and isopropyl
alcohol. All of the organic layers were deposited by using
thermal evaporation at a base pressure of <5 ꢂ 10ꢁ8 Torr.
Current density–voltage–luminescence (J–V–L) character-
istics of the PhOLEDs were measured simultaneously using
a Keithley 2400 programmable source meter and Spectra-
Scan PR650 (Photo Research). All the materials were
purified using train sublimation before use.
