Abstract

The cooperative assembly of mixed 2-aminoisonicotinate and adeninate ligands with Zn²⁺ centers generates a porous tetrahedral framework material with rich amino groups in the pores, which shows high CO₂ uptake at 0.1 bar, high enthalpy of CO₂ adsorption (40 kJ mol⁻¹) and excellent adsorption selectivity of CO₂ over N₂ under ambient conditions.
