Novel extended tetrathiafulvalenes (TTFs) with
hexa-2,4-diyne-1,6-diylidene spacers between the two 1,3-dithiole rings and
laterally appended alkynyl moieties for one- and two-dimensional
scaffolding were synthesised and investigated for their electronic
properties.
A selection of new acetylenic buildingblocks has been prepared and employed for construction of extended tetrathiafulvalenes (TTFs) and novel donor–acceptor molecules based on either diethynylethene (DEE), triethynylethene (TriEE), or tetraethynylethene (TEE) cores. The novel chromophores were studied for their redox, chromophoric, and structural properties, which have provided fundamental structure–property
A large conjugated chromophore containing four redox-active dithiafulvenes about a central anthraquinodimethane core and a new alkyne-extended tetrathiafulvalene has been synthesized by alkyne-alkyne coupling reactions. Studies of the optical and redox properties of these acetylenic scaffolds have been performed.
