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 (see image) and the hydrophobic vinyl backbone provides curvature for the formation of bilayer vesicles with a 1‐nm membrane thickness. The homopolymer vesicles act as a reservoir for both hydrophobic and hydrophilic molecules, individually or simultaneously.
