Design and synthesis of stable cuprous complexes bearing P∧N-type ligands for vapor-deposited organic light-emitting device

TADF: Enabling luminescent copper(i) coordination compounds for light-emitting electrochemical cells

“…Most of these are neutral and are of interest for OLEDs; selected examples which have been tested in OLED configurations are shown in Scheme 3. 36,64–96…”

The selective synthesis of N-arylbenzene-1,2-diamines or 1-arylbenzimidazoles by irradiating 4-methoxy-4′-substituted-azobenzenes in different solvents

“…Compounds with 1-phenyl-1 H -benzimidazole skeleton 1 have gained attention for a long time and been studied for the applications of platelet-derived growth factor receptor (PDGFR), 2 cyclooxygenase (COX), 3 and phosphodiesterase 10A 4 inhibitors, as well as for many optoelectronic materials. 5 N -Aryl-1,2-phenylenediamines are also important for synthesizing various benzimidazole derivatives, and 1,3,5-tris( N -phenyl-benzimidazol-2-yl)benzene (TBPI) is an important electronic material for OLED applications that is still widely used nowadays. 6 …”

Structural characterization and luminescence properties of trigonal Cu(i) iodine/bromine complexes comprising cation–π interactions

“…The bulky bis-diphenylphosphine-substituted benzimidazole ligand L was prepared in an overall yield of 67%, using a modified procedure reported recently by our group. 35,36 As illustrated in Scheme 1a, the fluorine-substituted precursor R was obtained from simple reductive cyclization. The target ligand L was readily prepared in high yields (85%) by treatment of R with potassium diphenylphosphide in tetrahydrofuran (THF).…”
