Binary Alloys of 2,5‐Disubstituted DCNQI Radical Anion Salts of Copper and Their Electrical Conductivity

Abstract

Electrocrystallization or even reaction with a copper wire leads to conversion of two 2, 5-disubstituted DCNQIs (1 and 2) into the alloy 3. Such an alloy displays metallic conductivity. Moreover, the phase transformation that normally causes the pure components to become semiconductors upon cooling can be suppressed through alloy formation.
