Stable binary nanohybrids based on all-inorganic halide perovskite encapsulated in porphyrinic Zr-MOF (PCN-222) are constructed for photoinduced electron transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization. The synergistic effect of perovskite and PCN-222 endows the photocatalyst with high-efficiency photogenic charge carrier separation and light absorption property. CsPbI 3 @PCN-222 (20%) is finally screened out as the oxygen and solvent-resistant photocatalyst for highly efficient photocontrolled polymerization of conjugated and unconjugated monomers under red to near infrared (NIR) light with high monomer conversion and narrow molecular weight distribution well-defined polymers (Đ < 1.20). Controllable polymers and ultrahigh molecular weight polymers (up to 1730000 g mol −1 ) are successfully obtained by chain extension and block copolymerization of various monomers. The constructed photocatalysts easily achieve excellent light and temporal control, and even show high MMA conversion with NIR light under a thick barrier.

CD-stabilized PdNPs supported on thermo-sensitive polymer brush grafted mussel-inspired Fe3O4@CFR core–shell magnetic nanospheres were constructed as a highly efficient recyclable nanocatalyst.

Carbon dots (CDs) with excellent optical properties are widely used in biomedicine, fluorescence sensing, and light‐emitting diodes (LEDs). However, it is still a challenge to prepare CDs that can stably emit red fluorescence in the water environment. In this study, polydopamine‐encapsulated luminescent carbon dots (CDs@PDA) with an encapsulating structure were synthesized at room temperature from p‐phenylenediamine‐derived red‐light CDs as the core and using mussel‐inspired chemical properties of polydopamine (PDA). In the binary system of water:ethanol = 1: 3 (volume ratio), the as‐prepared CDs@PDA had a dual emission of ultraviolet light (330 nm) and red light (640 nm) with the fluorescence quantum yields of 8.0 and 15.5%, respectively, at the same time under 285 nm light excitation. The as‐prepared CDs@PDA could be directly used for fluorescence selective sensing of 4‐nitrophenol (4‐NP) and Fe3+ through simultaneously quenching of ultraviolet and red fluorescence based on the internal filtration effect mechanism with detection limits of 3.44 and 3.75 μM, respectively. This research showed that PDA‐coated CDs can significantly improve the photoluminescence stability of CDs with new optical features. This means that the encapsulated structure of mussel chemistry is very helpful for expanding the application range of CDs in the water environment.
