Constructing POSS and viologen-linked porous cationic frameworks induced by the Zincke reaction for efficient CO₂ capture and conversion

Abstract

POSS and viologen-linked porous cationic frameworks (V-PCIF-X, X = Cl, Br) are constructed via the Zincke reaction between octa(aminophenyl)silsesquioxane and viologen linkers. The typical V-PCIF-Br has a high surface area with abundant ionic sites, micro-/mesopores and Si-OH groups, serving as an efficient porous adsorbent and metal-free catalyst for simultaneous CO2 capture and conversion.
