METHOD OF PRODUCING POLYDIACETYLENE THIN FILM

摘要

A method of producing a polydiacetylene thin film comprises spreading on a water surface a diacetylene compound having one or more conjugated diacetylene groups, subjecting the diacetylene compound to incomplete polymerization by irradiation with ultraviolet rays to an extent incapable of causing complete polymerization, transferring the spread film to a substrate to form a monolayer or built-up film thereon, and irradiating the transferred film with ultraviolet rays or an electron beam to complete the polymerization thereof.
