| Research Abstract |
For the realization of high-performance thin-film organic solar cells, a key issue is to develop self-assembly strategies that enable electron donor and acceptor molecules to form a heterojunction with a wide interface of hole and electron transporting nanoscale domains. Through the present work, we showed the first example of one-dimensionally connected organic nanostructures with dissimilar semiconducting properties. Along with this achievement, we serendipitously discovered that a polymer brush, bearing multiple mesogenic units in its side chains, can form a polymer film featuring a large-area homeotropic ordering of the polymer molecules. As an extension of this finding, we demonstrated a new photomechanical material, capable of converting light energy into a mechanical output.
