Anion-responsive tunable bulk-phase homochirality and luminescence of a cationic framework

Abstract

Reaction of a linear bi-chelating N-donor achiral ligand with Zn(II) afforded a homochiral cationic framework with six-fold one-dimensional helical chains. The compound showed selective anion exchange behavior with interesting anion-responsive tunable bulk-phase homochirality. The cationic framework also presented anion-driven variable luminescence and sorption behavior.

Keywords: anion exchange; bulk phase; cationic frameworks; homochirality; tunable luminescence.
