Phosphorescent iridium(III) complexes as lifetime-based biological sensors for photoluminescence lifetime imaging microscopy

Cyclometalated Spirobifluorene Imidazolylidene Platinum(II) Complexes with Predominant 3LC Emissive Character and High Photoluminescence Quantum Yields

“…Chemists can modify the structural design and thus rigorously tweak their photophysical properties. This qualifies these materials for application in organic light-emitting diodes (OLEDs) − and other technologies, for example, chemo- and oxygen sensors. − Novel technologies of this kind represent an imperative contribution of the scientific community to make climate change a success story since energy consumption can be drastically lowered utilizing (opto-)­electronic devices based on (metal-)­organic compounds. Recently, purely organic emitters based on spiro-conjugated donor–acceptor systems demonstrated excellent emissive properties, especially in the urgently sought-after blue-color spectrum.…”

A narrowband red-emitting asymmetric iridium(iii) complex featuring B- and N-embedded π-conjugation units: structure, photophysics and OLED application

“…Phosphorescent metal iridium(III) complexes, as excellent room temperature phosphorescent materials, are widely used in organic light-emitting diodes (OLEDs), [1][2][3][4][5][6][7][8][9][10] chemical sensing, [11][12][13][14][15] biological imaging, [16][17][18][19][20] photocatalysts for organic reactions, [21][22][23][24] etc. Especially for phosphorescent OLEDs which can be used in flat-panel displays and lighting sources, metal iridium complexes have more advantages, including a stable octahedral coordination structure, a suitable luminescence lifetime, an adjustable luminescence color, high luminescence efficiency and exciton utilization.…”

Geometric isomers of asymmetric rigid four-membered chelating ring based deep-red-emitting iridium complexes featuring three charged (0, −1, −2) ligands

“…As a kind of important optical material, phosphorescent iridium complexes with octahedral structure are widely used in various optical fields, including organic light-emitting diodes (OLEDs), 1–5 solar cells, 6–8 chemical sensing, 9,10 biological imaging, 11–13 photocatalysts, 14 etc . Notably, geometric isomers are very important and interesting in this class of octahedral coordination structures and can often lead to a great difference in the photophysical, electrochemical and thermodynamic properties of the complexes.…”
