Ionic liquids are considered as environmentally friendly solvents for various processes of organic synthesis. These non-toxic, non-volatile, and inflammable materials with controllable acid-base properties show promise in catalysis, including hydrocarbon conversion, electrocatalytic reactions, and polymer synthesis. Development of methods for synthesis of nanomaterials on the basis of conducting polymers, such as polyphenylenes is a challenging problem in view of growing interest to nanostructured materials and their application in such areas, as fuel cells, molecular computers, optoelectronics, biotechnology, sensors, etc. Electrocatalytic oxidative polycondensation of benzene, biphenyl, terphenyls, was studied in ionic liquids containing an N-alkylheterocyclic cation and chloroaluminate anions on Pt and electrodes. The polymer (oligomer) products were obtaned in ionic liquids at different conditions of synthesis (controlled current or potential; substrates). Linear polymers were obtained as products. It was shown that the degree of benzene polymerization increases in parallel with the electrode potential.
