Unprecedented binary semiconductors based on TCNQ: single-crystal X-ray studies and physical properties of Cu(TCNQX(2)) X=Cl, Br. Academic Article uri icon


  • Single crystals of a new structure type for the M+(TCNQ) - binary family are isolated from reactions of dihalogenated TCNQ derivatives and CuI ions (see figure; Cu: Pink C: black, N: blue, Br: orange, H: The new compound Cu(TCNQCI2) exhibits the highest con-ductivity of the M+(TCNQ) - series to date, despite the larger separation of TCNQCI2 units in the stacks. Conductive properties of Cu(TCNQX2) where X = CI, Br is attributed to charge-carrier transport through copper ions, which is unprecedented in M +(TCNQ) - materials.
