“…In this regard, the presence of a superbasic site in the catalyst is often required [146][147][148][149][150]. In addition to catalysis, recent applications in the field of material science [151][152][153], and for carbon dioxide capture and activation [154][155][156][157][158][159][160], seem to be promising. Many more general uses of molecules acting as superbases may be cited.…”

In this review, the principles of gas-phase proton basicity measurements and theoretical calculations are recalled as a reminder of how the basicity PA/GB scale, based on Brønsted–Lowry theory, was constructed in the gas-phase (PA—proton affinity and/or GB—gas-phase basicity in the enthalpy and Gibbs energy scale, respectively). The origins of exceptionally strong gas-phase basicity of some organic nitrogen bases containing N-sp3 (amines), N-sp2 (imines, amidines, guanidines, polyguanides, phosphazenes), and N-sp (nitriles) are rationalized. In particular, the role of push–pull nitrogen bases in the development of the gas-phase basicity in the superbasicity region is emphasized. Some reasons for the difficulties in measurements for poly-functional nitrogen bases are highlighted. Various structural phenomena being in relation with gas-phase acid–base equilibria that should be considered in quantum-chemical calculations of PA/GB parameters are discussed. The preparation methods for strong organic push–pull bases containing a N-sp2 site of protonation are briefly reviewed. Finally, recent trends in research on neutral organic superbases, leaning toward catalytic and other remarkable applications, are underlined.

“…Amidine and guanidine superbases were further studied with different alcohols and hexane revealing further possibilities for reversible capture of CO 2 . 30,32,37–39 A review thoroughly described the effect of alcohols, ionic liquids, and deep eutectic solvent on CO 2 capture. 39 On the other hand, the use of other organic solvents is not very well studied for CO 2 capture.…”

“…30,32,37–39 A review thoroughly described the effect of alcohols, ionic liquids, and deep eutectic solvent on CO 2 capture. 39 On the other hand, the use of other organic solvents is not very well studied for CO 2 capture. Furthermore, fundamental understanding of the synergistic solvent effect with superbases is lacking and further improvement of the superbase (SB)–CO 2 capture system remains highly challenging.…”
