The empiricism that extrinsic or doped materials universally perform much better than their intrinsic counterparts has been verified to be feasible in the adsorptive CO2 capture. Thus, a variety of N-doped solid adsorbents are well-engineered to adsorb CO2. However, the true nature of the N-doped sites in the aggregation state and the underlying mechanism of CO2 adsorption therein are difficult to determine In the present study, four well-defined azacyclo copolymers with peculiar textural characteristics, uniformly arrays and tunably effective N-doped sites were fabricated to exptl. determine the precise relation between adsorbed CO2 mols. and the N-doped sites incorporated into an adsorbent. With multifaceted quantum chem. computations, induction forces were proven to account for the improved CO2 adsorption on the N-doped sites instead of the conventionally assumed generalized acid-base interaction. The neg. electrostatic potentials were demonstrated to be the real cause for improving the CO2 adsorption and a robust indicator for the effectiveness of the N-doped sites. Besides, a precise linear function is proposed to quant. describe this subject-object relationship for the first time. In the experimental materials used by the author, we found 2,4,6-Trichloropyrimidine(cas: 3764-01-0COA of Formula: C4HCl3N2)
