Self-assembly and photopolymerization of a novel quaternary-ammonium functionalized diacetylene on noble metal nanoparticles: A comparative study
Applied Surface Science(2018)
摘要
•Ag/Au nanoparticles coated with the cationic diacetylene DAAMM are prepared.•Photopolymerization of chemisorbed DAAMM occurs in red and blue form simultaneously.•Polymerized nanohybrids have bilayered structure and are stable for months in water.•DAAMM assembly and photopolimerization are more effective on Au nanoparticles.•Unlike PCDA, optimal packing of DAAMM cannot be achieved on Ag and Au nanoparticles.
