Abstract

The growth and “pruning” of electrical connections between two platinum wires by electrocrystallization of the charge-transfer salt TTFBrx is reported. Crystals not involved in the connection can be removed by electrochemical reduction (see Figure). This method is a step towards the fabrication of complex structures without the use of a photolithographic or morphologic template.
