Abstract

Different ratios of octavinylsilsesquioxane (OVS) reacted with phenyl-substituted double-decker silsesquioxane (Ph-DDSQ) via the simple Friedel-Crafts reaction provides several innovative silsesquioxane-based porous polymers (PCS-ODs). The hybrid polymers show adjustable porosity (specific surface areas of 1235 m2 g−1 and large pore volumes >1.07 cm3 g−1). FTIR, SEM, BET, TGA, solid-state 13C and 29Si MAS NMR spectra were employed to fully characterize these hybrid materials. They display good adsorption capacities for neonicotinoid insecticides (imidacloprid [IMI], acetamidine [ACE] and thiamethoxam [THI]), with capacities up to 117 ± 2, 70 ± 1 and 61 ± 4 mg g−1, respectively. Dyes (Congo red [CR] and rhodamine B [RB]) can also be sufficiently removed, the adsorption capacities are 1822 ± 4 and 912 ± 3 mg g−1. In addition, PCS-ODs can be cycled at least five times.
