Set-up for combinatorial electrochemical synthesis and high-throughput investigation of organic semiconductor polymers for electronic devices

A novel automated set-up for combinatorial formation of conductive polymer films and investigation of their electrical properties is outlined. The set-up provides controlled electropolymerization on platinum or gold electrodes and consists of a dosing station, an electronic block for control and measurement and an electrode array. Conditions of electropolymerizations and measurements can be programmed by user and they are automatically, executed. Polymer layers are created on a electrode array with 96 single interdigital electrodes specially designed for four-point measurements to exclude contact effects. The first results obtained for electropolymerization of aniline are presented.
