Cyclodextrin-induced color changes in polymerized diacetylene Langmuir-Schaefer films

Abstract

We have observed the first example of a cyclodextrininduced color change of polymerized diacetylene film sensor. The PDA film, prepared from a diacetylene monomer containing a terminal anilide moiety was found to preferentially interact with alpha-cyclodextrin causing a color transition which is both time and concentration dependent.
