Synthesis, Langmuir and Langmuir-Blodgett films of a calix[7]arene ethyl ester

چکیده
Calixarenes are promising compounds to be used as ionophores and for molecular recognition. Their ability to form Langmuir and Langmuir-Blodgett (LB) films is of great interest in order to obtain small sensor devices which incorporate an active nanometric film. The p-tert-butylcalix[7]arene ethyl ester compound has been synthesised and its ability to form Langmuir and LB films has been shown. This macrocycle forms monolayers but it tends to form multilayers at higher compressions, as corroborated by AFM. BAM images show a uniform layer till the multilayer process occurs and a good correspondence with the features of the surface pressure-area

Molecular-level interactions of an azopolymer and poly(dodecylmethacrylate) in mixed Langmuir and Langmuir-Blodgett films for optical storage.
The applicability of azopolymers in optical storage can be extended through the use of nanostructured films produced with the Langmuir-Blodgett (LB) technique, but the film properties need to be optimized since these polymers generally do not form stable Langmuir films to be transferred onto solid substrates. Here, photoinduced birefringence was investigated for mixed Langmuir-Blodgett films fr...
متن کاملPyroelectric and conduction properties of Z-type calix[4] acid Langmuir-Blodgett films.
Non-centrosymmetric Z-type Langmuir-Blodgett (LB) films were prepared by transferring a calix[4] acid monolayer from a subphase of Millipore water (18 Momegacm(-1)) onto aluminised glass substrates. Electrical measurements were performed at room temperature on LB films with a sandwich structure comprising a 50 nm thick thermally evaporated aluminium film. A pyroelectric figure of merit of 2.23 ...

Single Langmuir-Blodgett (LB) bilayers derived from calix[n]arene-based surfactants (n = 4, 5 and 6) and poly(acrylic acid) (PAA) exhibit exceptional H(2)/CO(2) permeation selectivities. Evidence for the importance of ionic crosslinking and self-healing processes is presented.
متن کاملLangmuir Blodgett films of arachidic acid and N4 molecules: characterization and use in homeotropic alignment of N4
We study the behavior of a mixed Langmuir monolayer consisting of a fatty acid and a nematic liquid crystal. We demonstrate that the mixed monolayer successfully transfers as a Langmuir-Blodgett film and characterize the transferred film using UV spectroscopy. An important application of Langmuir-Blodgett films is in the alignment of liquid crystals for electro-optical applications, such as dis...

In the second half of the 20th century, scientists have been attracted to the design of thin solid films at the molecular level because of their potential for applications in the fields of biology and medicine. Two techniques dominated research in this area: Langmuir–Blodgett deposition and self-assembled monolayers (SAMs). Both Langmuir–Blodgett deposition, invented by Langmuir and Blodgett, a...
