Functionalities of such materials are significantly dependent on the supramolecular organization of the molecules and morphology of the resulting nanostructures. Through the control and modulation of molecular interactions, various kinds of self-assembled organic nanostructures with different morphologies such as fibers, tapes, wires, rods, tubes and particles have been reported. However, self-assembly of rationally designed molecular components into a prerequisite nanostructure, which enhances its functional properties, still remains a great challenge. Here we report on our recent approaches toward the alignment of conjugated polymers and the organization of conjugated molecules, which leads to the creation of various functional organic materials with optimized optoelectronic properties. In addition, we will report the direct observation of rotating motion of synthetic molecular machine.
