This chapter discusses a study examining poly-binaphthyl-20-crown-6 as receptor based molecule selective potentiometric electrodes for molecules containing 1,2-dihydroxybenzene moieties. A new potentiometric electrode for the determination of 1,2-dihydroxybenzene moieties such as catecholamines, known as ...
The enantioselectivity of CSP -1 is also better than those of some commercial R -(1,1'-binaphthyl)-20-crown-6 derivatives. Both the separation factors ( 伪 ) and the resolution ( R s ) are better than those of commercial crown ether-based CSPs [CROWNPAK CR(+) from Daicel] under the...
