title: A colorimetric organic chemo-sensor for Co²⁺ in a fully aqueous environment.
abstract: A new highly selective and sensitive colorimetric chemosensor 1 for Co(2+) was developed. The receptor 1 sensed Co(2+) by changing its color from yellow to orange in aqueous solution. Moreover, 1 could be used as a practical, visible colorimetric test kit for Co(2+).
