| Host | λ abs a (nm) | λ RTPL a (nm) | E g c (eV) | HOMOd (eV) | LUMOe (eV) | T 1 b (eV) |
|---|---|---|---|---|---|---|
| CzCbPy | 286, 338 | 355 | 3.50 | 6.12 | 2.62 | 2.98 |
| 2CzCbPy | 293, 337 | 399 | 3.38 | 6.06 | 2.68 | 2.97 |
a
Measured in toluene solution of 10−5 M at room temperature.
b
Measured in toluene solution of 10−5 M at 77 K. The triplet level was estimated from the first peakt of the phosphorescence spectra.
c
The optical band gap energy was determined from edge of the absorption spectrum.
d
HOMO levels were obtained using cyclic voltammetry.
e
LUMO levels were calculated from optical band gap and HOMO.
