Single‐Layer Transition Metal Dichalcogenide Nanosheet‐Assisted Assembly of Aggregation‐Induced Emission Molecules to Form Organic Nanosheets with Enhanced Fluorescence

Single-layer transition metal dichalcogenide nanosheets including MoS2, TiS2 and TaS2 can be used as novel platforms for the fluorescence enhancement of aggregation-induced emission fluorophores. The small organic AIE unit can be assembled into a two-dimensional sheet structure via a simple precipitation technique assisted by these monolayers. The resultant organic sheets possess a size of 0.2-2 μm and a thickness of 9-20 nm.
