Photochemical Electrocyclic Reactions: Stereochemistry

2.5K
The absorption of UV–visible light by conjugated systems causes the promotion of an electron from the ground state to the excited state. Consequently, photochemical electrocyclic reactions proceed via the excited-state HOMO rather than the ground-state HOMO. Since the ground- and excited-state HOMOs have different symmetries, the stereochemical outcome of electrocyclic reactions depends on the mode of activation; i.e., thermal or photochemical.

Summary

Researchers created a light-responsive surfactant system using fatty acids and a photoacid generator (PAG). UV light triggers self-assembly changes in the aqueous solution by altering pH levels.
