Efficient perovskite nanocrystal light-emitting diodes using a benzimidazole-substituted anthracene derivative as the electron transport material

Abstract

We report efficient perovskite nanocrystal LEDs based on a new electron transport material, <bold>BBIA</bold>, possessing high electron mobility of 4.17 × 10⁻⁴ cm² V⁻¹ s⁻¹. <bold>BBIA</bold>-based devices exhibit a nearly two-fold enhancement than TPBi counterpart.
