Control Over Emergent π-π-Interactions in Double-Dynamic Coordination Complexes Through a Nature-Inspired Coordination-Triggered System

• A complex self-assembly system based on coordination of dynamic imine/hemiacetal ligands isdemonstrated. Natural dipicolinic acid complexes are considered intercalants of certain bacterialDNA and implicated in thermal resistance of the dormant cell, and 6-formyl-2-picolinate was usedas building block. The dipicolinate-mimicking system showed an emergent and preferentialdynamic, drawbridge-style, π-π interaction effect to the opposing meridional ligand in octahedralcomplexes. The interactions proved to be influenced by the ligand net charge, the bridging arylgroup substitution, and the coordinating metal charge. The application scope of the effect isdiscussed.
