Supramolecular porous ionic network based on triazinonide and imidazolium: a template-free synthesis of meso-/macroporous organic materials via a one-pot reaction-assembly procedure

Abstract

A supramolecular porous ionic network (SPIN-1) was designed and prepared using a one-pot procedure, involving the quaternization of triimidazole triazine with cyanuric chloride followed by hydrolysis and in situ assembly. The structure of SPIN-1 was characterized by FT-IR, solid-state ¹³C CP/TOSS NMR, elemental analysis and XPS. SPIN-1 shows a BET surface area up to 263 m² g⁻¹ (average pore size 11 nm), and a CO₂ capture capacity of 24.7 cm³ g⁻¹, which is competitive for Carbon Capture and Storage (CCS).
