Highly efficient solution-processed blue organic light-emitting diodes based on thermally activated delayed fluorescence emitters with spiroacridine donor

Rising advancements in the application of PEDOT:PSS as a prosperous transparent and flexible electrode material for solution-processed organic electronics

“…It was found that the photoresist is completely processed with HFEs without any extra co-solvent, and that it does not have a destructive impact on the performance or the thickness of PEDOT:PSS films [19]. Another example of patterning similar to the work reported in [87], which was performed on the patterning of PEDOT:PSS OLED anodes via the conventional photolithography using an Ag interlayer, was reported by Kostianovskii et al, who employed a much simpler process of oxygen plasma etching instead of photolithography, and a protective layer formed from another noble but less expensive metal, copper (Cu). The patterned PEDOT:PSS films were applied as S/D electrodes for OFETs and yielded a high hole mobility of 0.29 cm 2 •V −1 s −1 with the contact resistance (R c ) values at least 10 times lower than those of goldbased OFETs [84].…”

“…They are both transparent and color-tuneable [86]. Although the first practical OLED appeared a little more than 30 years ago, the flexible OLEDs have been on the market for many years, and are the important components for the realization of the future flexible, wearable, foldable, and even biodegradable optoelectronic applications [85][86][87].…”

A trinuclear cobalt coordination complex constructed using novel triazine ligandsviaone-pot green synthesis: structural properties and biological evaluation

“…9 Recently, highly efficient solution-processed blue organic light-emitting diodes have been developed using a triazine acceptor as the primary component. 10 The electron-accepting nature of triazines makes them suitable for synthesising fluorescent green-light emitters with long device lifetimes and high electroluminescence efficiency. 11 While this class of compounds is important, systematic, feasible, and versatile methods for producing suitable 1,2,4-triazine skeletons are lacking.…”

Efficient Deep-Blue Electroluminescence Employing Heptazine-Based Thermally Activated Delayed Fluorescence

“…To get full-color displays or white-light OLEDs, the utilization of blue emitters is indispensable, and many kinds of molecular skeletons (e.g., boron-containing, diphenylsulfone-based, triazine-pyrimidinebased) have been developed [9]. To date, a large number of blue TADF emitters have been developed, whereas most of them belong to the sky-blue region [10][11][12][13][14][15][16][17]. Hence, highly efficient deep-blue TADF emitters are still urgently required.…”
