Abstract

Two aqueous lyotropic chromonic liquid crystals made from nickel(II) or copper(II) phthalocyananine tetrasulfonic acid tetrasodium salt are prepared with characterisation through optical polarising microscopy, X-ray diffraction and conductivity. These consist of ordered molecular aggregates of ~ 10 molecules, held together by π-π stacking. Electrochemistry within these dynamic, optically anisotropic columnar systems reveals that diffusion (physical transport or charge carrier hopping) can occur within two-dimensions. © 2012 Elsevier B.V.
