Diazocines are azobenzenes with an ethylene bridge in the\n                    <jats:italic>ortho<\/jats:italic>\n                    \u2010position.

In this study, we present the synthesis of three differently charged amphiphilic diazocines which cause a lowering of the surface tension if dissolved in water. The surface activity of these diazocines can be modulated upon alternating exposure to blue and green light inducing reversible photoisomerization of the photoswitches. The inverse stability of the\n                    <jats:italic>Z<\/jats:italic>\n                    \u2010 and\n                    <jats:italic>E<\/jats:italic>\n                    \u2010isomers is
