Direct grafting of poly(pentafluorophenyl acrylate) onto oxides: versatile substrates for reactive microcapillary printing and self-sorting modification

Abstract

Poly(pentafluorophenyl acrylate) was covalently attached to silicon oxide through the direct coupling of the reactive ester to surface silanol groups. Subsequently, reactive microcapillary printing (R-μCaP) and a one-pot, self-sorting postpolymerization modification reaction were used to generate patterns of spatially resolved chemical functionality.
