Coming together : Oligothymine is used as a template to self‐assemble complementary nonchiral naphthalene guests. Depending on the protonated state of the guest, left‐ or right‐handed DNA‐templated self‐assemblies are formed (see picture). The templated assembly processes were studied in detail with temperature‐dependent circular dichroism and UV/Vis spectroscopy.
