Z E isomerization processes in the Langmuir-Blodgett (LB) monolayer and in the bulk of the solution were compared. The molecules studied are crown ethers with the electro- and photoactive azobenzene moiety as part of the macrocyclic ring. The rates of the photoinduced E->Z isomerization and of the spontaneous thermal Z->E reaction were calculated on the basis of the electrochemical and spectroscopic...
