Rational design of a new class of polycyclic organic bases bearing two superbasic sites and their applications in the CO2 capture and activation process

Abstract

A new type of polycyclic organic superbases is reported with very high proton affinities in the gas phase and the pK(a) upto 45.8 units in acetonitrile. They have exhibited the 2nd pK(a) upto 44.4 units, which is the highest 2nd pK(a) reported till date. These organic superbases can be useful in the fixation of CO(2) released from different industrial sources.
