Colloidal quantum dots (QDs) with a wide color gamut and high luminescent efficiency are promising for next-generation electronic and photonic devices. However, precise and scalable patterning of QDs without degrading their properties and their integration into commercially relevant devices, such as digitally addressable QD light-emitting diode (QLED) displays, remain challenging. Here, we develop electronically optimized diazirine-based cross-linkers for nondestructive, direct photopatterning of QDs and, ultimately, building the active-matrix QLED displays.

- Surface chemistry is key for integrating colloidal nanocrystals (NCs) in optoelectronic devices like displays and sensors, but the role of photochemistry in this process is not fully understood.
- The study highlights how designing nitrene- and carbene-based photocrosslinkers can enhance the patterning capabilities and photophysical characteristics of quantum dots (QDs), crucial for maintaining their luminescent properties.
- The resulting patterned QLEDs achieved an impressive external quantum efficiency of approximately 12% and a lifespan exceeding 4800 hours, suggesting significant advancements in the integration of NCs for high-performance devices.
