Efficient Nondoped Pure Blue Organic Light-Emitting Diodes Based on an Anthracene and 9,9-Diphenyl-9,10-dihydroacridine Derivative

Organic light-emitting diodes (OLEDs) have been greatly developed in recent years owing to their abundant advantages for full-color displays and general-purpose lightings. Blue emitters not only provide one of the primary colors of the RGB (red, green and blue) display system to reduce the power consumption of OLEDs, but are able able to generate light of all colors, including blue, green, red, and white by energy transfer processes in devices. However, it remains a challenge to achieve high-performance blue electroluminescence, especially for nondoped devices. In this paper, we report a blue light emitting molecule, DPAC-AnPCN, which consists of 9,9-diphenyl-9,10-dihydroacridine and p-benzonitrile substituted anthracene moieties. The asymmetrically decoration on anthracene with different groups on its 9 and 10 positions combines the merits of the respective constructing units and endows DPAC-AnPCN with pure blue emission, high solid-state efficiency, good thermal stability and appropriate HOMO and LUMO energy levels. Furthermore, DPAC-AnPCN can be applied in a nondoped device to effectively reduce the fabrication complexity and cost. The nondoped device exhibits pure blue electroluminescence (EL) locating at 464 nm with CIE coordinates of (0.15, 0.15). Moreover, it maintains high efficiency at relatively high luminescence. The maximum external quantum efficiency (EQE) reaches 6.04 % and still remains 5.31 % at the luminance of 1000 cd m?2 showing a very small efficiency roll-off.

Highly efficient deep-blue fluorescence OLEDs with excellent charge balance based on phenanthro[9,10-: D] oxazole-anthracene derivatives

Two blue fluorescent materials, m-PO-ABN and p-PO-ABN, are newly synthesized by controlling the conjugation length based on different linkages of the meta or para position between the phenanthro[9,10-d]oxazole (PO) moiety and anthracene substituted with a cyano group. The two materials emit deep-blue light with a high photoluminescence quantum yield (PLQY) in solution state. Non-doped devices fabricated using m-PO-ABN and p-PO-ABN show the EL peaks at 448 and 460 nm corresponding to the Commission Internationale de L'Eclairage (CIE) coordinates of (0.148, 0.099) and (0.150, 0.164), respectively. The external quantum efficiency (EQE) values of the devices are 5.9% and 5.3% for m-PO-ABN and p-PO-ABN, respectively. Transient EL measurements and optical calculation results reveal that both materials exhibit good charge balance and triplet-triplet annihilation in the devices, which may originate from enhanced bipolar characteristics due to the insertion of PO and cyano moieties.

Nondoped blue fluorescent organic light-emitting diodes based on benzonitrile-anthracene derivative with 10.06% external quantum efficiency and low efficiency roll-off

In this manuscript, by utilizing limited conjugation of carbazole and easily realizing triplet-triplet annihilation properties of 4-(anthracen-9-yl)benzonitrile, two new blue materials 4-(10-(9-phenyl-9H-carbazol-3-yl)anthracen-9-yl)benzonitrile (3CzAnBzt) and 4-(10-(4-(9H-carbazol-9-yl)phenyl)anthracen-9-yl)benzonitrile (pCzAnBzt) were designed and synthesized. In both cases, these compounds exhibited small energy gap and orbit overlapped between excited state of Tm and Sn, which would accelerate the triplet-triplet annihilation process. Additionally, when these two compounds were used as emitters in nondoped devices, the triplet energy was utilized efficiently through triplet-triplet annihilation, excellent blue electroluminescence performances were achieved. The maximum external quantum efficiency values were 10.06% and 9.23% for 3CzAnBzt and pCzAnBzt, respectively. The efficiency roll-off for 3CzAnBzt and pCzAnBzt were very low, the EQEs still remained 8.97% and 7.10% at the luminescence of 1000 cd m-2. (0.14, 0.14) and (0.14, 0.10) are the Commission International de L'Eclairage coordinates for 3CzAnBzt and pCzAnBzt, respectively, at the voltage of 6 V. Up to now, the outstanding EL performances were the state-of-the-art compared to previously reported nondoped blue EL devices.

Efficient deep blue OLEDs with extremely low efficiency roll-off at high brightness based on phenanthroimidazole derivatives

Phosphorescent and thermally activated delayed fluorescence (TADF) emitters can break through the spin statistics rules and achieve great success in external quantum efficiency (over 5%). However, maintaining high efficiency at high brightness is a tremendous challenge for applications of organic light emitting diodes. Hence, we reported two phenanthroimidazole derivatives PPI-An-CN and PPI-An-TP and achieved extremely low efficiency roll-off with about 99% of the maximum external quantum efficiency (EQEmax) maintained even at a high luminance of 1000 cd/cm2 based non-doped devices. When doping the two materials in CBP (4,4′-bis(N-carbazolyl)-1,1′-biphenyl), the doped devices still exhibited excellent stability at high brightness with CIEy ≈ 0.07 and low turn-on voltage of only 2.8 V. The state-of-the-art low efficiency roll-off makes the new materials attractive for potential applications. It is the first time that the Fragment Contribution Analysis method has been used to analyze the excited state properties of the molecules in the field of OLEDs, which helps us understand the mechanism more intuitively and deeply.
