“…While the enthalpy gain of a complete cofacial approach of two aromatic systems may reach ∼0.35 V, 7 the overall free energy gain depends significantly on the linker connecting the two chromophores as well as the surrounding environment (i.e., solvent). In this context, an oxidation-induced molecular actuation, [10][11][12] i.e., reversible change in structure, conformation and/or physical properties in response to external stimuli, [13][14][15] represents an ideal case to probe the extent of cationic charge (i.e., hole) stabilization and structural/conformational reorganization in a set of model bichromophoric electron donors.…”
