Gas sensing using Langmuir - Blodgett films of a ruthenium porphyrin
نویسندگان
چکیده
We report on the Langmuir-Blodgett film formation and properties of a ruthenium porphyrin complex. Multilayer films may be transferred onto a variety of substrates. Reproducible deposition is indicated by both optical and electrical measurements. Ellipsometry reveals the thickness per layer to be 1.65 k 0.05 nm. A marked increase in the in-plane electrical conductivity of these layers is found upon exposure to nitrogen dioxide; this effect is found to be reversible at room temperature.

Langmuir 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...
متن کاملElectrochemical Properties of Langmuir-Blodgett Mixed Films Consisting of a Water-Soluble Porphyrin and a Phospholipid
Films of a water-soluble tetracationic porphyrin (TMPyP) and an insoluble phospholipid (DMPA), in a molar ratio TMPyP:DMPA ) 1:4, were transferred onto optically transparent indium tin oxide (ITO) electrodes, and cyclic voltammetry and visible spectroscopy were used to detected and quantify the presence of porphyrin on the ITO supports. We found the surface density of porphyrin deposited ranges...
متن کاملAdvantages of the Biomimetic Nanostructured Films as an Immobilization Method vs. the Carbon Paste Classical Method
Tyrosinase-based biosensors containing a phthalocyanine as electron mediator have been prepared by two different methods. In the first approach, the enzyme and the electron mediator have been immobilized in carbon paste electrodes. In the second method, they have been introduced in an arachidic acid Langmuir-Blodgett nanostructured film that provides a biomimetic environment. The sensing proper...
متن کاملThe Langmuir-Blodgett Technique as a Tool for Homeotropic Alignment of Fluorinated Liquid Crystals Mixed with Arachidic Acid
Some fluoro-substituted liquid crystals mixed with arachidic acid in monolayers formed at air-liquid (Langmuir films) and air-solid substrate (Langmuir-Blodgett films) interfaces were investigated. Molecular organization in Langmuir films was determined on the basis of the analysis of the shape of the surface pressure-mean molecular area isotherm and observations made by means of a Brewster ang...
متن کاملBiomedical Applications of Layer - by - Layer Assembly : From Biomimetics to Tissue
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...
