Macrocyclic Disulfides for Studies of Sensitized Photolysis of the S[BOND]S Bond



Sensitized photolysis: We describe a series of macrocyclic disulfides containing stiff stilbene (see scheme) as the intramolecular photosensitizer designed for fundamental mechanistic studies of sensitized photolysis of the S[BOND]S bond. Preliminary studies revealed weak temperature dependence of the quantum yields, which decreased exponentially with Boltzmann-weighted average separation between the S[BOND]S bond and stiff stilbene.
