Organic light-emitting diode having alleviated luminance reduction in low dynamic range

The present disclosure relates to an organic light-emitting diode which can operate at a low voltage with high efficiency and exhibits the effect of having an alleviated luminance reduction rate in a low dynamic range. More particularly, the organic light-emitting diode comprises: a first electrode; a second electrode facing the first electrode; and a light-emitting layer and a charge balance control layer arranged sequentially between the first and the second electrode, wherein the light-emitting layer includes at least one of amine derivative compounds represented by the following Chemical Formula A and the charge balance control layer includes at least one of anthracene derivative compounds represented by the following Chemical Formula B or C. The structures of Chemical Formulas A, B, and C are as defined in the specification.

Dibenzothiophene dioxide-benzofuro carbazole based bipolar host material for yellow and red phosphorescent OLEDs

2-(12H-benzofuro[3,2-a]carbazol-12-yl)dibenzo[b,d]thiophene 5,5-dioxide (DBT-INFUR) is a bipolar host material for yellow and red phosphorescent OLEDs. DBT-INFUR was designed and synthesized between dibenzothiphene acceptor and benzofuro carbazole donor with a yield of 60percent. We constructed two different devices, namely a yellow and a red phosphorescent OLEDs, and we compared the device properties with reference 4,4′-Bis(N-carbazolyl)-1,1′-biphenyl (CBP). DBT-INFUR based yellow phosphorescent OLED device exhibited maximum current and external quantum efficiencies of 41.07 cd/A and 16.5percent, respectively and which is better than that of reference CBP based similar device (27.66 cd A, 10.15percent). DBT-INFUR based red phosphorescent OLED (12.44percent) revealed higher efficiencies when compared to the reference (7.64percent) device. The bipolar DBT-INFUR showed excellent host properties with yellow and red phosphorescent devices.

Visible Light-Induced Borylation of C-O, C-N, and C-X Bonds

Boronic acids are centrally important functional motifs and synthetic precursors. Visible light-induced borylation may provide access to structurally diverse boronates, but a broadly efficient photocatalytic borylation method that can effect borylation of a wide range of substrates, including strong C-O bonds, remains elusive. Herein, we report a general, metal-free visible light-induced photocatalytic borylation platform that enables borylation of electron-rich derivatives of phenols and anilines, chloroarenes, as well as other haloarenes. The reaction exhibits excellent functional group tolerance, as demonstrated by the borylation of a range of structurally complex substrates. Remarkably, the reaction is catalyzed by phenothiazine, a simple organic photocatalyst with MW 200 that mediates the previously unachievable visible light-induced single electron reduction of phenol derivatives with reduction potentials as negative as approximately - 3 V versus SCE by a proton-coupled electron transfer mechanism. Mechanistic studies point to the crucial role of the photocatalyst-base interaction.
