Effect of substituent groups for formation of organic-metal hybrid nanowires by charge-transfer of tetrathiafulvalene derivatives with metal ion

Effect of substituent groups on a tetrathiafulvalene (TTF) unit for formation of organic-metal hybrid nanowires was studied. Depend on the substituent groups, the nanowires were obtained as a precipitate just by mixing TTF derivatives and HAuCl4 in CH3CN solution at room temperature via electron transfer reaction between the TTF derivatives and a gold ion. To precede favorably hybrid nanowire formation, increase planarity and introduction of strong interaction on the TTF derivatives are required.
