Asymmetrically difunctionalized dibenzo[b,d]furan-based hole blocking materials for high-performance blue phosphorescent organic light-emitting diodes

Low-Temperature Cross-Linkable Hole Transport Materials for Solution-Processed Quantum Dot and Organic Light-Emitting Diodes with High Efficiency and Color Purity

“…The cross-linkable organic HTMs, 1-DTPA, 2-DTPA, 3-DTPA, and 4-DTPA, comprising DBF as the core and TPA as the end group with disubstituted vinyl moieties as cross-linking functional groups, were synthesized. DBF was chosen as the core owing to its low cost, high thermal stability, and structural tunability, allowing the introduction of various substituents. − In addition, substitution in the DBF core significantly improves hole transport characteristics. A well-known hole transport disubstituted vinyl TPA unit was introduced at the 1, 2, 3, and 4 positions of the DBF core.…”

Furan-Containing Quinoidal Compounds for High-Performance Copper/Silver Electrode-Based n-Channel Organic Transistors

“…Compared with thiophene, furan has merits in many aspects such as fluorescence, solubility, , and renewability . However, furan-containing organic semiconductors are relatively rare, though some of them have found applications in organic solar cells, ,− organic light-emitting diodes, , and organic transistors. − Table S1 lists the chemical structures and transistor performances of some typical furan-containing organic semiconductors. It is clearly seen that most of the them show hole or ambipolar transport properties.…”

High-Efficiency Simplified Orange and White Organic Light-Emitting Devices Based on a Platinum(II) Complex

“…However, achieving high efficiency in OLEDs is still an open research problem, which prevents universal production in long-term development [ 4 , 5 ]. In order to improve the efficiency, extraordinary efforts have been made using a variety of novel organic materials or by adopting novel device structures [ 6 , 7 ].…”
