Facile synthesis and characterization of iridium(iii) complexes containing an N-ethylcarbazole-thiazole main ligand using a tandem reaction for solution processed phosphorescent organic light-emitting diodes

A new series of highly efficient phosphorescent Ir(iii) complexes, which have potential applications in solution processable phosphorescent organic light-emitting diodes (PhOLEDs), were synthesized and their photophysical, electrochemical, and electroluminescent (EL) properties were investigated. The Ir(iii) complexes, including (Et-Cz-Tz)2Ir(pic), (Et-Cz-Tz) 2Ir(pic-N-O), (Et-Cz-Tz)2Ir(EO2-pic), and (Et-Cz-Tz)2Ir(EO2-pic-N-O), are comprised of linked N-ethylcarbazole (Et-Cz) and thiazole (Tz) units as the main ligand (Et-Cz-Tz) and picolinic acid (pic) and picolinic acid N-oxide (pic-N-O) as ancillary ligands. In addition, some of the Ir(iii) complexes contain an ethylene oxide solubilizing group attached to the ancillary ligands via a tandem reaction. High performance, solution processable PhOLEDs, fabricated using (Et-Cz-Tz) 2Ir(EO2-pic), were observed to have a maximum external quantum efficiency of 6.08% and a luminance efficiency of 10.98 cd A -1. This is the first report on the use of EO2-pic and EO2-pic-N-O ancillary ligands for the synthesis of solution processable Ir(iii) complexes via a tandem reaction. The performances of the PhOLEDs based on these Ir(iii) complexes correlate well with the theoretical properties predicted by using density functional theory calculations.

Triphenyl phosphine oxide-bridged bipolar host materials for green and red phosphorescent organic light-emitting diodes

Two wide band gap functional compounds of phenylbis(4-(spiro [fluorene-9,9'-xanthen]-2-yl)phenyl)phosphine oxide (2SFOPO) and (4-(9-ethyl-9H- carbazol-3-yl)phenyl)(phenyl)(4-(spiro[fluorene-9,9′-xanthen]-2-yl)phenyl)phosphine oxide (SFOPO-CZ) were designe

Iridium complex for oxygen sensing and preparation method thereof

The invention discloses an iridium complex for oxygen sensing and a preparation method thereof, wherein the iridium complex is a dimer iridium complex. As 4,4 '- dimethyl -2, 2' - bipyridine ligand or 4 - ((decyloxy) methyl) -4 '- methyl -2 and 2' - bipyridyl ligand and hexafluorophosphate are prepared from the reaction raw materials, the obtained product can respectively target cell membranes and enter cytoplasm. The compound has good stability in a physiological environment, and can be stably existing without interference pH value variation.

Nickel-Catalyzed Borylation of Aryl- and Benzyltrimethylammonium Salts via C-N Bond Cleavage

By developing a mild Ni-catalyzed system, a method for direct borylation of sp2 and sp3 C-N bonds has been established. The key to this hightly efficient C-N bond borylative cleavage depends on the appropriate choice of the nickel catalyst Ni(COD)2, ICy·HCl as a ligand, and the use of 2-ethoxyethanol as the cosolvent. This transformation shows good functional group compatibility and can serve as a powerful synthetic tool for gram-scale synthesis and late-stage C-N borylation of complex compounds.
