Abstract
Blends of poly(acrylic acid)-block-polystyrene (PAA-b-PS) copolymers and poly(ethylene oxide) (PEO) homopolymers in which PAA and PEO interact via hydrogen bonds were used as pre- cursors of nanoporous PS thin films with cavities decorated by PAA blocks. The presence of free carboxylic acid groups inside the pores was evidenced by fluorescence spectroscopy after reacting them with a diazomethane functionalized fluores- cent dye. These nanoporous thin films were then used as tem- plates for the preparation of dense arrays of silica nanodots.
