Research Abstract

The unique supramolecular self-supporting membranes were prepared by highly selective cycloaromatization (SCAT) of one-handed helical polyphenylacetylene membrane. The hardness of supramolecular self-supporting membrane was influenced to the original structure of one-handed helical polyphenylacetylene membrane. And also, the SCAT of polyphenylacetylene by LED lamp was investigated. The rate of SCAT by LED was a little faster than that of the xenon lamp. Because the lifetime of LED lamp is longer than xenon, the SCAT of polyphenylacetylene by LED lamp was more effective.
