This book addresses the manufacturing methods, characteristic tubular morphologies, diverse functions, and potent applications of organic tubular architectures prepared or self-assembled from rationally designed molecular building blocks. The hollow cylindrical structures with high-aspect ratios are capable of creating unique functions that can be differentiated from well-known self-assembled nanostructures such as organic nanofibers, nanoribbons, and nanorods. Encapsulation, stabilization, transportation, release, and their cooperative functions pave the way for innovative chemical,...
