pH-sensitive unimolecular fluorescent polymeric micelles: from volume phase transition to optical response

Chem Commun (Camb). 2014 Jan 25;50(7):823-5. doi: 10.1039/c3cc48046a.

Abstract

Unimolecular fluorescent micelles of star polyelectrolytes with a perylenediimide core are very sensitive to changes in pH values. The pH-responsive behavior relies on the ionization or deionization of the star polyelectrolytes, which causes a reversible volume phase transition and optical response.
