Langmuir Blodgett Films

Structural and electronic properties of pentacene/pentacenequinone thin films prepared on various solid-state substrates by the Langmuir–Blodgett technique are reported. Amorphous structure of the prepared films has been proved by XRD measurements. Oxygen-related defects have been identified in the Langmuir–Blodgett films as a consequence of the exposure of pentacene Langmuir layer to air. Crystallization induced by thermal treatment of the prepared amorphous thin films has been observed. Electronic properties of pentacene/ pentacenequinone Langmuir–Blodgett films have been investigated in the contact-less architecture using electrochemical techniques. The energy band diagram of the amorphous pentacene/pentacenequinone Langmuir–Blodgett film on a metallic surface was constructed from the obtained electrochemical data.

The preparation and properties of tert-dodecanethiol protected gold nanoparticles amenable to very rapid surface functionalization by associative mechanism is described. The new material can be easily prepared by controlling the reaction time, because only a limited but enough number of tert-dodecanethiol to stabilize the gold clusters is bond to the surface until about an hour. Accordingly, it can be isolated as a solid and handled much like the highly stabilized Brust-Schiffrin analogues, but reacted very rapidly with any molecular species containing one or multiple functional groups such as thiol, disulfide, pyridine, etc., These characteristics are ideal for the preparation of a variety of new organic–inorganic hybrid nanomaterials by coordinative self-assembly. This possibility was illustrated using meso-tetra(4-pyridyl)porphyrin, which promptly bonded to the reactive protected gold nanoparticles generating a solid that can be grown as thin films with layer-by-layer control on a suitably modified surface.

Different LB films of poly(octadecene-co-maleic anhydride), PMAO, poly(styrene-co-maleic anhydride) partial 2 butoxy ethyl ester cumene terminated, PS-MA-BEE, and Gemini surfactant ethyl-bis(dimethyl octadecylammonium bromide), 18-2-18, have been used to study the effect of the substrate coating on the surface self-assembly of CdSe quantum dots (QDs). Results show that all the “coating molecules” avoid the 3D aggregation of QDs observed when these nanoparticles are directly deposited on mica. Different morphologies were observed depending on the molecules used as coatings, and this was related to the surface properties, such as wetting ability, and the morphology of the coating LB films.
