Abstract

Abstract Carboxyl group functionalized hollow microporous organic nanospheres (HMONs-COOH) were successfully synthesized by hyper-crosslinking reaction between polylactide-b-polystyrene (PLA-b-PS) diblock copolymers and 2,4,6-tris(bromomethyl)mesitylene as well as subsequent alkaline KMnO4 oxidation. The synthesized HMONs-COOH possess the high special surface area, robust organic framework and hierarchically porous structure, which shows highly catalytic activity in the Friedel-Crafts alkylation of indole with aldehydes and outstanding adsorption efficiency toward cationic dyes.
