Pre-synthetic redox control of structure and properties in copper TTFtt coordination polymers.

ABSTRACT: Conductive coordination polymers (CPs) with sulfur-based ligands offer strong metal-ligand interactions and redox tunability, making them promising candidates for electronic applications. Tetrathiafulvalene-2,3,6,7-tetrathiolate (TTFtt) is a particularly attractive ligand. However, its strong metal-ligand covalency leads to rapid irreversible metal coordination, limiting control over structure and morphology. Here, we demonstrate structural control in Cu TTFtt CPs using a pre-synthetic redox control strategy. Two new copper-based CPs, CuTTFtt and Cu₂TTFtt, have been synthesized and thoroughly characterized from differentially oxidized TTFtt synthons. CuTTFtt forms a 1D chain, while Cu₂TTFtt adopts a 2D ribbon-like structure. Detailed spectroscopic studies confirm the
