Three new iridium complexes with β-diketonate ancillary ligands were synthesized as emissive materials for organic light-emitting devices.
A new iridium(iii) complex containing a coumarin derivative as the cyclometalated ligand (L) and carbazole-functionalized β-diketonate (Cz-acac-allyl) ancillary ligand, namely, Ir(iii) bis(3-(pyridin-2-yl)coumarinato-N,C(4))(1-(9-butyl-9H-carbazol-3-yl)hept-6-ene-1,3-dionato-O,O) [Ir(L)2(Cz-acac-allyl)], was firstly synthesized emissive complex. Then three phosphorescent polyhedral oligomeric silsesquioxane (POSS) materials, consisting of carbazole moieties covalently attached to core were...
Red organic light-emitting diodes using a rhenium(I) bipyridyl complex, fac-[ClRe(CO)3(trans-4-methyl-4′-(2-4-octadecyloxylphenyl)vinyl)-2,2′-bipyridine] (Re-mopvb), as an emitter were fabricated. The optimized device has bilayer structure of indium-tin oxide∕poly(N-vinylcarbazole): 2 wt. % Re-mopvb (80 nm)∕2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (50 nm)∕LiF (1 nm)∕Al (150 nm). Although no photoluminescence from in the room-temperature solution appeared due to photoinduced...
A novel tetradentate oxime chelating ligand, 3,3′‐Dihydroxy‐2,2′‐[Ethylenedioxybis(nitrilomethyli‐dyne)]diphenol (H4L), and its mononuclear copper(II) complex [Cu(H2L)] · 2H2O have been synthesized characterized by elemental analysis, IR, UV‐vis 1H‐NMR etc. The X‐ray crystallography of indicates that the asymmetric unit consists discrete two crystallizing waters. four atoms donor set (N1, N2, O1, O2) in N2O2 coordination sphere Cu1 approximately lie a plane. dihedral angle between plane...
A new iridium complex containing coumarin derivative as a cyclometalated ligand (1L) and carbazole-functionalized β-diketonate (2L) the ancillary ligand, namely, Ir(III)bis(3-(pyridin-2-yl)coumarinato-N,C4)(1-(9-butyl-9H-carbazol-3-yl)-4,4,4-trifluoro-butane-1,3-dionato-O,O) (Ir(1L)2(2L)), was synthesized. The crystal structure of Ir(1L)2(2L) determined via combined wide angle X-ray diffraction (WAXD) transmission electron microscopy (TEM), which showed π–π interactions molecules stacking...
Two new iridium organometallic compounds based on acetylacetone derivative ligands containing carrier-transporting groups, Ir(L)2(acac-Ox) and Ir(L)2(acac-Cz), where L = 3-(pyridin-2-yl)coumarinato N, C4, acac-Ox 3-(4-(5-(4′-tert-butylphenyl)-1,3,4-oxadiazole)benzyl)-pentane-2,4-dionate acac-Cz 3-((4-(9H-carbazol-9-yl)phenyl)methyl)pentane-2,4-dionate, have been successfully synthesized characterized by elemental analysis, 1H NMR FT-IR. The structure of the free ligand was established...
Two new Ir(<sc>iii</sc>) complexes containing a functionalized benzimidazole ligand (<bold>L</bold>) were successfully synthesized for use in green phosphorescent organic light-emitting diodes.
Two new POSS materials with an emissive Ir(<sc>iii</sc>) complex and carbazole units were successfully synthesized. Their photophysical electrochemical properties, thermal stabilities solution processed light-emitting devices investigated.
Two-dimensional (2D) materials have attracted greatest attention in the past years. In this study, we report 2D conjugated polymeric nanocrystals, polyhedral oligomeric silsesquioxanes (POSS) covalently bonded with main chain of poly(3-hexylthiophene) (P3HT) without utilization a template or an exfoliation protocol. The crystal structure POSS-P3HT are systematically investigated and confirmed by wide-angle X-ray diffraction, transmission electron microscopy, scanning atomic force microscopy...
