Abstract
AbstractWe developed a catalyst‐free, atom‐economical interfacial amino‐yne click polymerization to in situ synthesize new aggregation‐induced emission luminogen (AIEgen)‐based free‐standing porous organic polymer films at room temperature. The crystalline properties of POP films were confirmed by powder X‐ray diffraction and high‐resolution transmission electron microscopy. The good porosity of these POP films was proved by their N2uptake experiments. The thickness of POP films can be easily regulated from 16 nm to ≈1 μm by adjusting monomer concentration. More importantly, these AIEgen‐based POP films show bright luminescence with high absolute photoluminescent quantum yields up to 37.8 % and good chemical and thermal stability. The AIEgen‐based POP film can encapsulate an organic dye (e.g., Nile red) to further form an artificial light‐harvesting system with a large red‐shift (Δλ=141 nm), highly efficient energy‐transfer ability (ΦET=91 %), and high antenna effect (11.3).
