The
design and synthesis of some cyclometalated iridium(III) complexes
containing quinoline-type ligands as ancillary ligands are reported.
The emission spectra of Ir(III) complexes containing a quinolinolate
(6, 8, 10) moiety exhibit a
single emission peak at ca. 590 nm, resulting in a red colored emission.
However, Ir(III) complexes containing 8-sulfonamidoquinoline ligands
(11, 13–21) exhibit
two different emission peaks (dual emission) at ca. 500 nm and ca.
600 nm upon excitation at 366 nm, resulting in a red-colored emission
for 11 and a pale yellow-colored emission for 14–18 at 298 K. Especially, a white emission was
observed for 19 at 298 and 77 K in dimethyl sulfoxide.
The mechanistic studies based on time-dependent density functional
theory calculations and time-resolved emission spectroscopy suggest
that this dual emission originates from two independent emission states.
