Controlling Colorimetric Reversibility of Polydiacetylene Supramolecules

摘要

We have investigated colorimetric reversibility of polydiacetylene Supramolecules derived from a variety of functionalized diacetylenic lipids. Polydiacetylene vesicles prepared from PCDA-mBzA 1, which has terminal m-carboxyphenylamido groups, was found to show complete reversibility upon thermal stimulation. The origin and the nature of the reversible thermochromism were demonstrated by preparing analogs of PCDA-mBzA 1.
