Iodine-induced electrical conductivity of novel columnar lanthanide metal–organic frameworks based on a butterfly-shaped π-extended tetrathiafulvalene ligand†
Abstract
Novel columnar lanthanide metal–organic frameworks (Ln-MOFs) based on a butterfly-shaped electron-rich π-extended tetrathia-fulvalene ligand (ExTTFTB) were synthesized and their electronic properties were investigated. Upon iodine-induced ligand oxidation, the Tb-MOF displayed ca. 100-fold higher electrical conductivity (5 × 10−7 S m−1) than the neutral pristine MOF.
