Highly discriminating cycloaddition: An unexpected [2+2] cycloaddition in self‐assembled cation OPV‐monolayered vesicles is described. Remarkably, the photochemical reaction is chemo‐, regio‐, and stereoselective, which is most likely the result of the well‐controlled supramolecular organization of the OPV units in the monolayer.

A single strand of DNA templates a supramolecular strand of chromophores, yielding a new type of DNA hybrid. In this hybrid construct, an oligothymine is used as the template to which a supramolecular stack of naphthalenes or oligo(phenylene)vinylenes equipped with a complementary diamino triazine unit is hydrogen-bonded.

aggregate in chiral stacks, as can be concluded from UV–vis, fluorescence and CD spectroscopy. Temperature dependent measurements showed for OPV1 a transition at 50 °C from a chiral aggregated state to disordered aggregates. In the case of bolaamphiphilic OPV2, the transition at 55 °C between those states is a less cooperative process. The chiral order in the assemblies of the bolaamphiphiles can be influenced
