- ... The cucurbituril (CB) host–guest complexations of a series of zwitterionic “Good's” biological pH buffers have been investigated in aqueous solution by means of ¹H NMR spectroscopy. The cyclohexylammonium buffers bind very strongly (KCB[₇] = 10⁷ to 10⁸ dm³ mol⁻¹), while the morpholinium (10² to 10³ dm³ mol⁻¹) and piperazinium (10³ to 10⁴ dm³ mol⁻¹) buffers have binding constants several orde ...
