英文摘要： Now continuous interest has been devoted to the fabrication of one-dimensional conjugated polymer microtube materials because of their high conductivity, ease of preparation and operation, good environmental stability, and a large variety of applications in molecular wires, chemical sensors, biosensors, and electronic devices. To data, the conjugated polymer microtube materials have been prepared by various methods including "the hard-templates method" by using zeolite channels, tract-etched polycarbonate and porous alumina membranes, "the soft-templates method" by using the micelle, surfactant, liquid crystal and inverse micro-emulsion, and "the self-assembly method". Moreover, the interfacial polymerization, oligomer-assisted and nanofiber seeding method have been also used to synthesize the conjugated polymer microtube materials. Polydiacetylene, classified as a one-dimensional conjugated polymer, possesses many interesting features in their electronical and optical properties. However, the design and synthesis of novel one-dimensional polydiacetylene microtube assembled from the nanometer-sized vesicle still remain a challenge. In this application, we will develop a novel facile and effective approach to fabricate polydiacetylene microtube based on the cooperation effect of the vesicles served as the basic s
