Tetrathiafulvalene-s-tetrazine: versatile platform for donor–acceptor systems and multifunctional ligands†‡
Abstract
The structurally characterized tetrathiafulvalene-1,2,4,5-tetrazine donor–acceptor system shows redox tuneable intramolecular charge transfer, solvatochromic and electrochromic behaviour. Attachment of a dipicolyl-amine chelating unit affords a multifunctional
