Langmuir-Blodgett Films of Supported Polyester Dendrimers

Abstract

Amphiphiles with a dendritic structure are attractive materials as they combine the features of dendrimers with the self-assembling properties and interfacial behavior of water-air affinities. We have synthesized three generations of polyester dendrimers and studied their interfacial properties on the Langmuir films. The behavior obtained was, as a rule, the lowest generation dendrimers behaving like traditional amphiphiles and the larger molecules presenting complicated isotherms. The Langmuir films of these compounds have been characterized by their surface pressure versus molecular area (π/A) and Brewster angle microscopy (BAM) observations.

Interfacial Behavior of Oligo(Ethylene Glycol) Dendrons Spread Alone and in Combination with a Phospholipid as Langmuir Monolayers at the Air/Water Interface

“…The Langmuir–Blodgett (LB) technique is commonly used for the fabrication of ordered monolayers by transfer onto solid substrate surfaces. Information about the microstructure of monolayers of dendrimers prepared by the LB technique has been obtained using X-ray, atomic force microscopy (AFM), Brewster angle microscopy (BAM), and neutron reflectivity [14,16,17,18].…”
