Low-Temperature Cross-Linked Hole Transport Layer for High-Performance Blue Quantum-Dot Light-Emitting Diodes

“…Otherwise, the partial dissolution of underneath layers may cause severe nonemissive recombination problems in QLEDs . An effective way to avoid interlayer mixing is to utilize the orthogonal solvents, but this approach restricts the choice of solvents for hole transport layers (HTLs) and quantum dots (QDs). − As such, the use of cross-linkable materials to prepare HTLs is a promising strategy that allows for the production of films with excellent solvent resistance, without limiting the solvents used in subsequent layer deposition. − Therefore, the development of cross-linkable HTLs is necessary for solution-processed QLEDs.…”
