Oxidation-induced activation of chalcogen bonding in redox-active bis(selenomethyl)tetrathiafulvalene derivatives

Chalcogen bonding (ChB) interactions are investigated in two new -SeMe substituted tetrathiafulvalene (TTF) derivatives, RTTF(SeMe)(2) (R = Me-2, SCH2CH2S). Upon oxidation to 1 : 1 cationic radical salts, Se atoms are engaged in highly linear ChB interactions with bromide anions, demonstrating the efficient sigma-hole activation of selenium through redox-active substituents.
