Precision Nanoconfined Self-Assembly of ACQ Carbon Dots for Enhanced Solid-State Fluorescence.

ABSTRACT: Carbon dots (CDs) are promising fluorescent nanomaterials, however, they are often hindered by aggregation caused quenching (ACQ) in solid-state application because of close π-π stacking interactions. Furthermore, the challenges still exist in the development of CDs-based solid-state fluorescent materials with stable structure and high fluorescence intensity. To address this challenge, a general and robust polymer directed nanoconfined self-assembly strategy is developed, enabling the fabrication of regular morphology, structurally ultra-stable and solid-state fluorescent CDs assemblies using hydrophilic star-liked di-block copolymer unimolecular micelles as templates. The absolute photoluminescence quantum yield (PLQY) of these fluorescent solid-state CD assemblies reaches 21.46%, signifi
