Reversible and pH-Sensitive Vesicles from Amphiphilic Homopolymer Poly(2-(4-vinylphenyl)pyridine)

The sigma bond between the 2-phenyl pyridine head groups and the vinyl backbone of poly(2-(4-vinylphenyl)pyridine) allows for free rotation of the head groups in response to the polymer's environment and the hydrophobic vinyl backbone provides curvature for the formation of bilayer vesicles with a l-nm membrane thickness. The homopolymer vesicles act as a reservoir for both hydrophobic and hydrophllic molecules, individually or simultaneously. (Figure Presented). © 2010 WILEY-VCH Verlag GmbH & Co. KGaA.
