This study has led to the discovery of a receptor molecule that can be used to distinguish between two types of PDA supramolecules that undergo colorimetric changes. α-CD was found to promote a blue-to-purple or blue-to-red color transition of only those PDAs that are colorimetrically irreversible. In contrast, α-CD was unable to induce a color change of PDAs that display reversible thermochromism behavior. The results of this effort, which provide useful information about headgroup interactions in PDA supramolecules, have resulted in an important diagnostic methodology. Specifically, if α-CD causes color transition, the PDA is not colorimetrically irreversible. |
