Langmuir and Langmuir−Blodgett Monolayers of Molecular Tweezers and Clips
Langmuir, 2007Molecular clips and tweezers are able to selectively bind electron-deficient aromatic and aliphatic substrates. By means of pressure-area isotherms and Brewster angle microscopy (BAM), the self-association process and phase behavior of dimethylene-bridged molecular clips and tetramethylene-bridged molecular tweezers each substituted with two acetoxy ...

Langmuir and Langmuir–Blodgett films of aromatic amphiphiles
Soft Materials, 2021Amphiphiles are molecules that contain two discrete segments – a water-soluble hydrophilic part (head-group) and a water-insoluble hydrophobic part (tail).

Langmuir and Langmuir-Blodgett Films of Metallosupramolecular Polyelectrolyte-Amphiphile Complexes
Langmuir, 2005A detailed analysis of a metallosupramolecular polyelectrolyte-amphiphile complex (PAC) at the air-water interface is presented. Langmuir isotherms, Brewster angle microscopy, and X-ray reflectance and diffraction methods are employed to investigate the structure of the Langmuir monolayers.

Langmuir and Langmuir–Blodgett films of quantum dots
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2006Abstract Trioctylphosphine oxide (TOPO) capped CdSe and (CdSe)ZnS quantum dots (QDs) were prepared. The surface chemistry behavior of both QDs at the air–water interface was carefully examined by various physical measurements. Stable Langmuir films were formed for both QDs.

Cavitation of Langmuir monolayers
Physical Review E, 2002Cavitation in liquid expanded and liquid condensed Langmuir monolayers induced by laser heating or microbubble coalescence is studied experimentally using fluorescence and Brewster angle microscopy. The kinetics of hole closure of two-dimensional (2D) gaseous cavitation bubbles exhibits a decelerated dynamics for cavities surrounded by a liquid ...

Science, 1994
The controlled transfer of organized monolayers of amphiphilic molecules from the air-water interface to a solid substrate was the first molecular-scale technology for the creation of new materials. However, the potential benefits of the technology envisioned by Langmuir and Blodgett in the 1930s have yet to be fully realized.

Photoreactions and lateral patterning in Langmuir and Langmuir–Blodgett films
The Chemical Record, 2007AbstractReversible morphological changes occur with photoisomerization of azobenzene in Langmuir–Blodgett (LB) films complexed with polycations, which contradicts an implicit assumption of the concept of free volume that two‐dimensional film structures are preserved during the photoisomerization. J‐aggregates of chromophores are formed by two processes.
