A redox-responsive supramolecular amphiphile fabricated by selenium-containing pillar[5]arene-based host–guest recognition

Abstract

A novel molecular recognition motif was built between a selenium-containing pillar[5]arene and a pyridinium bromide salt in water. Furthermore, a supramolecular amphiphile based on this new host–guest recognition motif with redox-responsiveness was fabricated and applied in the controlled release of small molecules.
