Stimuli-responsive metal-directed self-assembly of a ring-in-ring complex†
Abstract
Concentration, temperature and/or solvent polarity control the speciation on the metal-directed self-assembly of a ditopic pyridyl ligand L with cis-protected Pd(II) metal centers. This results into a controllable dynamic system, involving a [Pd2L2]6+ metallacycle and a [Pd4L4]12+ ring-in-ring complex.
