Revolutionary Organic Ligands for Perovskite Nanocrystal Displays
- Revolutionize display technology with new organic ligands for perovskite nanocrystals. Enhance stability, patterning, and charge transport for high-quality light emitting diodes.
Researchers from multiple universities have developed organic ligands for perovskite nanocrystals (PNCs) to improve their stability and patterning for display applications. The functional ligands, AzL1-Th and AzL2-Th, contain photocurable azide moieties that enhance charge transport properties and maintain a high photoluminescence quantum yield (PLQY). The team successfully demonstrated the use of AzL1-Th in crosslinked PNC light emitting diodes, showing the potential of photocurable ligands for micro-patterning PNC films without damaging them.
The "all-in-one" organic ligands offer efficient dispersion, photocuration, and charge transport capabilities by utilizing electron-rich thiophene rings. AzL1-Th attached to CsPbBr3 PNCs exhibited high charge carrier mobility and enabled the PNCs to achieve a high PLQY of 88%. The CsPbBr3 PNCs attached to AzL1-Th were easily crosslinked after UV light irradiation, allowing for successful patterning of AzL1-Th-PNC films and crosslinked PNC LEDs.
