Vapor Sublimation and Deposition to Fabricate a Porous Methyl Propiolate-Functionalized Poly--xylylene Material for Copper-Free Click Chemistry.

Conventional porous materials are mostly synthesized in solution-based methods involving solvents and initiators, and the functionalization of these porous materials usually requires additional and complex steps. In the current study, a methyl propiolate-functionalized porous poly--xylylene material was fabricated based on a unique vapor sublimation and deposition process. The process used a water solution and ice as the template with a customizable shape and dimensions, and the conventional chemical vapor deposition (CVD) polymerization of poly--xylylene on such an ice template formed a three-dimensional, porous poly--xylylene material with interconnected porous structures.
