Self-Assembly of a Fluorescent Chiral Zinc(II) Complex That Leads to Supramolecular Helices

The chiral Zn(II) complex [ZnLCl2], 1 {L = 4-methyl-2,6-di[(S)-(+)-1-phenylethyliminomethyl] phenol}, self-assembles via C−H···Cl hydrogen bonding into supramolecular helices. Complex 1 exhibits emission in solution at room temperature in the visible range.
