Electrical conductivity in hexaalkoxytriphenylenes

Abstract

Abstract Triphenylenes containing six side‐chains O(CH 2 ) n CH 3 , n  3‐5, have been prepared and doped with iodine. The compounds show mesophases which have been characterised by differential‐scanning calorimetry and small‐angle X‐ray scattering. Samples doped with iodine show an electrical conductivity of 10 −4 ‐10 −3 Ω −1 ·m −1 , which is slightly higher in the columnar mesophase than in the other phases.
