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 CO₂ released from different industrial sources.
