Abstract:
By incorporating methyl groups to introduce steric hindrance and utilizing hydroxyl groups to establish intramolecular hydrogen bonds, we synthesized a covalent organic framework (COF) with aggregation-induced emission (AIE) behavior and near-infrared (NIR) luminescence (λem = 657 nm). The integration of the innovative COF with LED chips enabled the fabrication of high-quality red and white organic phosphor-converted light-emitting diodes (LEDs). This work provides a new way to explore COFs to construct low-cost, high-performance, and eco-friendly LED devices.
