This work deals with the behavior studied through the Langmuir-Blodgett technique of a synthetic fluorescent macrocycloureide substituted with twoC18-saturated alkyl chains, the distearylmacrocycloureide (DSM). TheDSMmonolayer exhibited a peculiar behavior when compressed, and a well-defined monolayer to bilayer transition was observed on the π-A isotherms.
