Abstrakt: The magnetic properties of charge-transfer (CT) complexes and cation radical salts of tetrathiafulvalene (TTF) derivatives bearing two different radical substituents were investigated. Preferential spin interactions occurred between TTF cation radical (TTF+•) and an acceptor anion radical for the CT complexes, and between two TTF+•’s for the cation radical salts, respectively. In addition, the magnitude was markedly different by the kind of radical substituent, which behaved as an isolated spin.
