Construction of a supramolecular antibacterial material based on water-soluble pillar[5]arene and a zwitterionic guest molecule.

A new antibacterial system (HG) based on the host-guest chemistry between pillar[5]arene and a zwitterionic guest was fabricated. The HG complex displayed excellent antibacterial and biofilm formation inhibition and dispersal activities against E. coli , S. aureus and MRSA.
