Single-molecule force microscopy was used to monitor the mechanical and structural changes in the cis↔trans transition of individual azo

• linear ω0 parameter to the two cyclic series, using it as a fixed value in the fitting and comparing the obtained coupling constants. These amount to JI = 1.355 eV and JII = 1.388 eV and reveal a slightly better electronic coupling for macrocycles of series II and therefore a reduced transition energy
