dc.description.abstractThe search for new molecular architectures to improve the efficiency of sensors and optoelectronic devices is fundamental to enhance the effectiveness of nanostructured materials. In this present work, a di-ureasil hybrid compound (DUPTS) was spread at the air-water interface in order to form Langmuir monolayers. Phosphotungstic acid, H3PW12O40, PWA inserted in the aqueous subphase stabilized the formation of DUPTS as a stable Langmuir film, as showed with surface pressure and surface potential-area isotherms, rheological measurements, polarization modulation reflection-absorption spectroscopy, and Brewster angle microscopy. The monolayers were transferred to solid supports as Langmuir-Blodgett films and presented different patterns of heterogeneity as observed with atomic force microscopy, with the morphology dependent on the presence of PWA and on the kind of solid support surface.en
