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.
本文报道了一种新型多环有机超强碱，其在气相中的质子亲和力非常高，在乙腈中的 pK(a)值高达 45.8 个单位。它们表现出的第 2 个 pK(a)值高达 44.4 个单位，这是迄今为止报道的最高的第 2 个 pK(a)值。这些有机超强碱可用于固定来自不同工业源的 CO(2)。
