“…Iridium complexes have catalyzed significant research interest due to their various applications such as bioimaging, [1][2][3][4][5][6] organic photovoltaic cells, [7][8][9][10] and catalysis. [11][12][13][14] Particularly, the implementation of iridium complexes as emitters in phosphorescent organic light-emitting diodes (PhOLEDs) has attracted great attention.…”

Novel H-bond-rich iridium (III) complexes with different systems of cyclometalating ligands bearing the general formula [Ir(C^N)2(N^N)] were synthesized, characterized and their photophysical properties measured. The incorporated guanidine moieties allow us to introduce a hydrogen-bonding array for the formation of self-assembled iridium hydrogen-bonded systems. Through a series of UV-Vis binding studies we demonstrated the host-guest chemistry of these systems display high levels of colour tuneability. These hydrogen-bond interactions were also shown to have significant impacts on chromaticity, quantum yields and lifetimes with emphasis on energy transfer studies based on this second-sphere coordination approach.

“…To date, cyclometallated iridium complexes emitting in green and blue regions have reported high quantum efficiencies. 23 On the other hand, orange and red emitting iridium complexes typically suffer from lower quantum yields since the radiative rate constant (kr) has a dependence on the excited state energy 5 and it usually decreases with longer emission wavelengths. 24 Blue iridium complexes are still under investigation for their application in the display and lighting industry as they have still relatively low efficiencies compared to standard Ir(III) red and green devices.…”

Novel iridium (III) complexes with different systems of cyclo-metallating ligands bearing the general formula [Ir(C^N)2(N^N)] were synthesized, characterized and their photophysical properties measured. Incorporation of guanidine moieties into iridium complexes allows us to introduce a hydrogen-bonding array for the formation of self-assembled iridium hydrogenbonded systems. Through a series of UV-vis binding studies we demonstrated the host-guest chemistry of these systems display high levels of colour tuneability. The introduction of these hydrogen-bond modifications was also shown to have significant impacts on chromaticity, quantum yields and lifetimes with emphasis on energy transfer studies based on secondsphere coordination methodology.

“… 3 Iridium is well known for its cyclometallating properties, which causes C–H bond activation in the cyclometallating class of ligands. A vast range of phosphorescent Ir( iii ) complexes were prepared from cyclometallating ligands and were studied for their application in numerous fields, such as organic light emitting diodes (OLEDs), 5,6 solar light harvesting devices, 7,8 and anticancer agents. 9,10 …”
