A new chromogenic 1,10-phenanthroline bearing picrylamino residue displays a striking lithium ion-selective shift in maximum absorbance in the presence of base upon addition of lithium ions; upon lithium complexation the color of solution changes from pale yellow to brownish red, the color density being dependent on lithium ion concentration.
