The synthesis and characterisation of Langmuir-Blodgett film forming TCNQ adducts.
… materials on the subphase and their resultant Langmuir-Blodgett (LB) film fabrication was studied. The abrupt change in molecular orientation in LB films of the gamma-bridged adducts occurring at R= C[15]H[31] and above was not seen in the more flatly orientated alpha-bridged adducts. Further …

Synthesis of functional polyimide and its application in nanostructured films
… wedges in formation of porous structure in bulk film was investigated. Lower density and higher extend of butanol intrusion of the modified polyimide bulk film after thermal treatment shows uniform porous structure. Langmuir-Blodgett films were fabricated with the as-synthesized polyimide and the …

Electrical characterization of large-area donor-acceptor molecular junctions
… molecular junctions show current rectification. Langmuir-Blodgett deposition onto thermally evaporated gold yielded four out of the five monolayers. The fifth system was as a monolayer formed by self-assembly onto template-stripped gold. Of the four Langmuir-Blodgett films studied, three had …

Synthesis and molecular properties of zwitterionic adducts of TCNQ and other related compounds
… zwitterions on the subphase and their resultant Langmuir-Blodgett film forming ability was also studied. However unlike the TCNQ-based materials the fluorinated adducts have been shown to be poor LB film forming materials.

Optical and thermal characteristics of thin polymer and polhedral oligomeric silsesquioxane (POSS) filled polymer films
… technique for characterizing ultrathin polymeric films. By conducting the experiments in different ambient media, multiple incident media (MIM) ellipsometry, simultaneous determinations of a film's thickness and refractive index are possible. Poly(tert-butyl acrylate) (PtBA) films serve as a model …

MODULATION AND INTERACTIONS OF CHARGED BIOMIMETIC MEMBRANES WITH BIVALENT IONS
… signaling events. In addition, I explain the Langmuir-Blodgett film balance (LB) system as tool to study lipid membranes and lipid interactions. In the second chapter, I describe my work on the lateral compressibility of PtdIns(4, 5)P2, PtdIns and DOPG monolayers and its modulation by bivalent …

Synthesis, redox properties, and langmuir monolayer formation of selected 3d- and 4d- metalloamphiphiles
… and electrochemical properties together with the film forming properties. These compounds thereby find potential towards the fabrication of responsive films. This dissertation confers the synthesis and analysis of film forming properties of various redox-active metalloamphiphiles. Two new azido …

Imaging of Heterogeneous Langmuir -Blodgett Monolayer with Compressive Sensing Sum Frequency Generation Microscopy and Brewster Angle Microscopy
… to chemically study surface heterogeneity. Langmuir Blodgett (LB) monolayers are widely used as standard models for cell membranes.

Quartz Crystal Microbalance Studies of Dimethyl Methylphosphonate Sorption Into Trisilanolphenyl-Poss Films
… a CWA simulant, into trisilanolphenyl-POSS (TPP) films has previously been characterized with reflection absorption infrared spectroscopy, x-ray photoelectron spectroscopy, and uptake coefficient determinations [1]. In our study, the quartz crystal microbalance (QCM) is used to study the sorption …

The Reactivity of Chemical Warfare Agent Simulants on Carbamate Functionalized Monolayers and Ordered Silsesquioxane Films
… applied toward the creation of well-ordered thin films containing carbamate linkages. In addition, novel trisilanolphenyl-polyhedral oligomeric silsesquioxane (POSS) molecules were used to create Langmuir-Blodgett films containing reactive silanol groups that have potential use as sensors and …

Self-Assembled Host-Guest Thin Films for Functional Interfaces
… a new or improved function. "Host-guest" thin film complexes are composed of "host" molecules attached the substrate surface, either through physisorption or covalent bonds, with cavities for the inclusion of desired "guest" molecules for the functionalization of the surface. Two methods for …
