Structural Dependence of Catenand Effect: Thermodynamic and Kinetic Modulation of Catenane Coordination Properties via Ring-size and Exocyclic Substituent Variation.

ABSTRACT: Although the effects of ligand interlocking on specific features of coordinated metal were first reported in 1980s', strategies to precisely control these features through structural modifications of interlocked ligands remains underdeveloped. This limitation has hindered the broader exploitation of this unique class of coordination compounds across various fields of transition metal chemistry. Through a systematic comparison and detail analysis of a series of Cu^I catenane complexes, we show in this work that the size of the interlocked rings and exocyclic substituents are important structural parameters that regulate the exposure of the metal coordination sphere, which also influences the coordination geometry, electronic structures, spectroscopic, photophysical and electrochem
