title: A chiral, porous, organic cage-based, enantioselective potentiometric sensor for 2-aminobutanol.
abstract: A new enantioselective potentiometric sensor containing R-type chiral porous organic cage CC9 as the chiral selector was designed for the assay of 2-aminobutanol. Optimized membrane electrodes displayed a linear dynamic range from 10-3~ 10-1mol·L-1with a detection limit of 2.5 × 10-4mol·L-1and a Nernstian response of 27 ± 0.5mV·decade-1toward S-2-aminobutanol within the pH range 7.0-10.0. The potentiometric enantioselectivity coefficient ( logKS,RPot) of this sensor was -1.333, indicating that the porous organic cage-based electrode exhibited good discrimination toward S-2-aminobutanol over R-2-aminobutanol.
