Quinonoid π-extended tetrathiafulvalenes (TTFs)

subject

description

Publisher Summary Tetrathiafulvalene (TTF) is a fascinating planar πelectron-donor molecule with a broad range of potential applications. TTF and its derivatives play an important role in the field of organic conductors forming charge-transfer (CT) complexes and radical cation salts (Bechgaard salts) with a huge variety of electron-acceptor molecules and anions in the search for electrically conducting and superconducting materials. The chapter focuses on highly π-extended electron donors with p-quinodimethane structures as interesting precursors of materials with non-conventional properties. The first dimeric examples of π-extended TTF derivatives connected through an oxygen atom are also presented along with some works directed toward the preparation of TTF derivatives covalently attached to an electron acceptor moiety, including fullerene C60 as an acceptor—through conjugated or nonconjugated spacers—in the search of new electronic applications of TTF such as second-order nonlinear optical (NLO) properties or its potential use for molecular electronic devices.
