Cyclometallated ionic iridium(III) binuclear complexes with a bisphenanthroline bridging ligand: Synthesis and photophysical properties

New iridium(III) ionic binuclear complexes, in which iridium-containing cyclometallated fragments are bound by a bridging bisphenanthroline ligand were synthesized. The compounds obtained show intensive photoluminescence of yellow and yellow-green colors.
