Design and synthesis of a noninnocent multitopic catechol and pyridine mixed ligand: Nanoscale polymers and valence tautomerism

The design and synthesis of a new redox-active ligand combining catechol and pyridine units have allowed the achievement of cobalt-based nanoscale coordination polymer particles in a single-step exhibiting a switchable valence tautomeric behavior and thermal hysteresis. The combination of polymerizing capabilities with redox-active responses in a unique ligand leads to the formation of nanoparticles exhibiting a gradual valence tautomeric interconversion in the 35-370 K temperature range. Using one single ligand to obtain these nanoparticles facilitates possible nanostructure formation methodologies.This work was supported ICN2 acknowledges support from the Severo Ochoa Program (MINECO, Grant SEV-2013-0295).
