(a) Isomerization of hydrazone 17 and the associated equation for the E:Z ratio at PSS (ε_λ(E/Z) = extinction coefficient at wavelength of irradiation λ; ϕ_λ = quantum yield of indicated isomerization process at wavelength λ). (b) “Linear” network for the assembly of monomer B under continuous irradiation in which the supramolecular polymer is at equilibrium with the dispersed monomer. (c) Cyclic network for the assembly of monomer B under continuous irradiation in which the supramolecular polymer is at a NESS (primed kinetic constants refer to processes involving the aggregated state). (d) Schematic potential energy diagram for ester exchange reaction (Quantitative Descriptions of Simple Reaction Networks) 1. highlighting that the overall cycle is thermodynamically downhill and takes place on a single surface. (e) Schematic potential energy diagram for the isomerization of 17 highlighting that the conversion of Z-17 to E-17 is thermodynamically uphill and that the process takes place on two different surfaces (nrd = non-radiative decay).
