In an article, author is Mei, Qunbo, once mentioned the application of 17852-52-7, Name is 4-Hydrazinylbenzenesulfonamide hydrochloride, molecular formula is C6H10ClN3O2S, molecular weight is 223.68, MDL number is MFCD00052262, category is phthalazine. Now introduce a scientific discovery about this category, Formula: https://www.ambeed.com/products/17852-52-7.html.
Two novel bis-cyclometalated iridium(III) complexes, Ir(ECPC)(2)(pic) and Ir(TPC)(2)(pic) (HECPC, 3-(4-(9H-carbazol-9-yl)phthalazin-1-yl)-9-ethyl-9H-carbazole; HTPC, 4-(4-(9H-carbazol-9-yl)phthalazin-1-yl)-N,N-diphenylaniline, pic = 2-picolinic acid) were synthesized in moderate yield under mild synthetic conditions, and their electrical and photophysical properties were characterized with respect to their application as a phosphorescent emitter in polymer light-emitting diodes (PLEDs). The devices based on these complexes with the structure of ITO/PEDOT:PSS (40 nm)/70%PVK:30%PBD:x% iridium(III) complex (70 nm)/TPBI (30 nm)/Ba (1.5 nm)/Al (120 nm) were fabricated with highly external quantum efficiency. The device based on Ir(ECPC)(2)(pic) exhibited a maximum external quantum efficiency of 16.3% and a luminance of 1484 cd/cm(2); while the device based on Ir(TPC)(2)(pic) showed a maximum external quantum efficiency of 11.9% and a Commission International de L’Eclairage (CIE) coordinates of (0.695,0.289). The results showed that the two new bis-cyclometalated iridium(III) complexes can be used as emitters and applied in saturated red phosphorescent organic light-emitting diodes (PHOLEDs).
