In addition, we confirmed the possibility of using such a miniaturized cell for screening of organoboron compounds as potential ionophores. We tested nineteen different organoboron compounds including representatives from arylboronic acids, oxaboroles, cyclic borinic acids (dibenzoborinines) and triarylboranes and showed that the results are analogous to the ones obtained with the standard cell. All tested compounds could attach a fluoride ion to a boron atom to form an anion. The ion transfer can be easily observed at the interface of two immiscible solutions using voltammetry technique.
