Charge Transportation and Chirality in Liquid Crystalline Helical Network Phases of Achiral BTBT‐Derived Polycatenar Molecules

First examples of multichain (polycatenar) compounds, based on the π-conjugated [1]benzothieno[3,2-b]benzothiophene unit are designed, synthesized, and their soft self-assembly charge carrier mobility investigated. These terminated by new fan-shaped 2-brominated 3,4,5-trialkoxybenzoate moiety, form bicontinuous cubic liquid crystalline (LC) phases with helical network structure over extremely wide temperature ranges (>200 K), including ambient temperature. Compounds short chains show an achiral phase double network, which upon increasing chain length, is at first replaced a tetragonal 3D then mirror symmetry broken triple phase. In networks, capability bypassing defects provides enhanced compared to imperfectly aligned columnar phases, transportation non-dispersive, as only rarely observed for LC materials. At transition semicrystalline phase, conductivity further almost one order magnitude. addition, isotropic formed beside elongation removed hexagonal
