A general multiscale simulation procedure is proposed to accurately predict the uptakes of pollution gases such as CO 2 , SO 2 , H 2 S, and CO in one of the most investigated porous organic cages CC3 by using a sophisticated force field vdW3 fitted by double hybrid functional (B2PLYP) with a dispersion correction (D3) separately for gas–gas and CC3‐gas interactions. The fitted vdW3 was used in grand canonical Monte Carlo simulations. Good comparison with the coupled cluster single and double excitation and the perturbative triples (CCSD(T))/complete basis set (CBS) limit interaction energies make the B2PLYP‐D3 results reliable for our purpose. The good agreement of simulated CO 2 loading with experimental one and the low deviation in the fitting procedure for H 2 S and CO make our approach available in predicting gases in novel porous materials. © 2013 Wiley Periodicals, Inc.
