Chiral Tetraarylmethane Derivative with Metal‐Coordinating Ability

Abstract

The synthesis of a chiral tetraarylmethane derivative is reported. The solvent effect on the CD spectra was observed for the solution. This is attributable to a molecular design with three of four aryl groups have the nitrogen atom at the ortho position with respect to the central carbon atom. This unique design was realized when a variety of transition metal ions were added to the solution, showing different patterns of CD spectra. This cover picture is a personified translation of this experimental observation. The cartoon also implies a law of human nature: two pupils reacting differently to one thing.
