An act of viologens: The study of new polymer nanoparticles that consist of viologen cavitands linked with styrene bridges is reported. The nanoparticles feature temperature-controlled binding and release of substrates, as shown by the fluorescent dye rhodamine B (see scheme). Changing the temperature from 25 to 40 °C resulted in a significant enhancement in the permeability of the nanoparticle shell for the passage of rhodamine B.
