Vapor-Phase Fabrication of a Maleimide-Functionalized Poly-p-xylylene with a Three-Dimensional Structure

摘要: A vapor-phase process, involving the sublimation of an ice substrate/template and vapor deposition a maleimide-functionalized poly-p-xylylene, has been reported to synthesize advanced porous material, with readily clickable chemical interface properties, perform Michael-type addition maleimide functionality for conjugation thiol group. In contrast conventional poly-p-xylylenes on solid surface that forms thin film coatings, process herein additionally results in dynamic sublimating (template), rendering construction three-dimensional, porous, poly-p-xylylene. The seamlessly exploits refined polymerization from maleimide-substituted [2,2]paracyclophane ensures preservation transformation final poly-p-xylylene products. functionalization production were completed single step, thus avoiding complicated steps or post-functionalization procedures are commonly seen approaches produce functional materials. More importantly, equipped provides rapid efficient route click toward thiol-terminated molecules, reaction can be performed under mild conditions at room temperature water solution without need catalyst, initiator, other energy sources. introduced vapor-based enables straightforward synthesis approach not only pore-forming structure three-dimensional but also situ-derived group, conduct covalent thiol-terminal which abundant biological environments. These materials expected have wide variety new applications.
