Surface Plasmons and Visible Light Iniferter Initiated Polymerization for Nanolocal Functionalization of Mesoporous Separation Layers

Although the technological relevance of mesoporous ceramic polymer hybrid materials is well accepted, missing functionalization concepts enabling 3D nanoscale local control placement into materials, including thin films, and ideally using controlled polymerization techniques limit application potential. Here, nanolocal separation layers controlled, visible light iniferter initiated allowing responsive locally limited to irradiated spot introduced. Thereby, two sensitive iniferters, s-p-trimethoxysilylbenzyl-S´-dodecyltrithiocarbonate 4-cyano-4-((dodecylsulfanylthiocarbonyl)sulfanyl)pentanoic acid, are developed for films in a grafting from through approach. close proximity plasmonic field source demonstrated by combining these polymerizations with optical near modes, such as localized surface plasmon resonance (LSPR). As location LSPR can be placing metal alloy nanoparticles film thicknesses adjusted, this strategy applied precise positioning polymers three dimensions thus reduces gap precision functional group between biological nanopores.
