At the end of its tether : A charge‐transfer (CT) dyad with a trimethylene tether forms a folded or extended monomer or a dimer depending on the conditions (see picture). Both dimer formation at low temperatures and monomer confinement by inclusion in a cyclodextrin cavity greatly enhance the anisotropy ( g ) factor of the CT transition of the complex.
