文摘

An -quartz-mimetic chiral coordination network of [Ag(L¹)(CF₃SO₃)]_n (L¹ = 5,5'-bipyrimidine), after treatment with PF₆^- anions,undergoes a solution-state structural transformation toward [Ag(L¹)(PF₆)]_n with a cristobalite-mimetic chiral structures. Thisstructural transformation is accompanied by substantial enhancement in the fluorescent intensity and in the second-harmonic-generation response. The results also demonstrate an effectivedesign strategy based on the spontaneous resolution route forthe preparation of chiral architectures.
