Facile synthesis of enantiopure chiral molecular rectangles exhibiting induced circular dichroism

The facile syntheses of enantiopure molecular rectangles using 1,8-bis(trans-Pt(PEt3)(2)(NO3))anthracene and optically pure D- or L-tartrate are reported in high yields. These self-assembled macrocycles are unique examples where the phenomenon of induced chiral dichroism (ICD) has been observed in chiral metallosupramolecular assemblies.
