Lyotropic Liquid Crystalline Mesophase Governs Interfacial Molecular Orientation of Conjugated Polymer Thin Films

Interfacial out-of-plane molecular orientation critically influences the electronic performance of organic semiconductor thin films. The appearance of a lyotropic liquid crystalline (LC) mesophase during solution coating of conjugated polymers may directly determine the interfacial out-of-plane molecular orientation. However, a lack of studies on the packing structure of the liquid crystalline mesophase and its evolution to the solid state...
