The homoleptic complex can be used to detect phosphate ions in micromolar concentrations either spectrophotometrically or with the naked-eye. To our knowledge, this is the biomimetic detection system with the highest affinity known to date for selective, naked-eye based phosphate recognition under physiological conditions.</p> </div></div></div>
