This book was released on 2014 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: LANKA D.W. WICKRAMASINGHE ARACHCHILAGE August 2014 Advisor: Professor Cl©Łudio N. Verani Major: Chemistry (Inorganic) Degree: Doctor of Philosophy The silicon-based microelectronic industry has made remarkable technological advancements. Among these, new generation consumer electronics, telecommunication devices, and high performance data processing smart devices are of special interest. At present, electronic components existing on a single silicon chip grow rapidly, and soon the miniaturization process of electrical components will face limitations due to heat dissipation. Therefore, as an advanced alternative for silicon-based electronic components, the investigation of nanoscale molecular electronic devices is of great importance. This dissertation research is focused on the development of redox-active asymmetric metallosurfactants as potential candidates for molecule-based electronics. Asymmetric donor-acceptor type [D-A] molecules are promising candidates to study the current rectification behavior. In order to address this phenomenon, a series of ligands with phenolate moieties and, their gallium(III), iron(III), and manganese(III) complexes with [N2O3] and [N2O2] coordination environments were synthesized and structurally characterized using multiple methods. Ligands were designed with different electron-donating and electron-withdrawing substituents, to modulate structural, chemical, and physical properties, such as geometry, spectroscopic, redox, film formation, and electrical properties. As an initial attempt, low symmetry gallium(III) and iron(III) complexes with [N2O3] binding moieties were developed. Different alkyl substituents are introduced to the phenylenediamine moiety of the main ligand structure to allow for film formation of the metal complexes. The electrochemical properties of gallium(III) complexes show ligand-based redox processes, while the iron(III) complexes show metal- and ligand-centered redox processes.

Download or read book Electrochemistry of Monolayer Mediated Redox active Species with Ultrafast Voltammetry written by Md Hossain and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The work presents a theoretical framework to analyze and capture the role of energetics and electrochemical environment on electrochemistry of redox-active species in solution. The model system utilized in this study consists mainly of an ensemble of redox molecules/ nanoparticles in an aqueous solution each connected to a metal electrode by a bridging monolayer. In this configuration, redox processes are mostly outer-sphere in nature and are dictated by electron tunnelling across the metal-liquid interface. The transfer processes are simulated via voltammetry with a recently developed model based on quantum transport, which shows excellent agreement with the typically utilized Marcus- Gerischer rate picture in electrochemistry. Using this theory, a distinct connection between interfacial coupling and applied scan rate has been established. This connection reveals that by applying ultrafast scan rates, the active transfer rate can be forced to closely follow the ideal rate constants defined by the governing rate equations. This effectively leads to a significant suppression of electrode kinetics that broadens the resulting current peak towards infinity. Firstly, the peak potential of the derivative of this plateaued current response shows a good agreement with the effective redox-energy level of the reactants and the reorganization energy of the system. Secondly, the percent amount of redox conversions calculated from the current profiles at different scan rates show a consistent evolutionary pattern. This pattern is utilized to extract the effective coupling strength of the metal-monolayer-particle interface. This formulation is then implemented in a model redox system represented by armchair Carbon nanotubes to characterize its energy level structure near the Fermi level. In a solvated environment, the key energetic contributions to such a level arise from the discrete electron-kinetic levels spacing [delta][epsilon]TN and the Coulomb charging energy U of a redox-species, and the nuclear reorganization energy [lamda] of the overall system. Because of nuclear reorganization, a current peak in voltammetry that usually marks the access of an electron to a redox electronic level tends to occur at a potential that underestimates that electronic level. The proposed theory in this work presents a method to overcome this limitation by combining slow and ultrafast scan rates in voltammetry. The method correlates the resulting current-peak potentials to each of the above fundamental energetics consumed during the associated electron transfer. In slow scan rate regime, successive peak separations mainly represent the alternate consumption of [delta][epsilon]TN +U and U. The influence of reorganization energy [lamda] on a current profile is captured by ultra- fast scan rates. Based on this formation, the technique is used to extract the electronic structure of the model armchair carbon nanotube system. Calculations at the ultrafast regime capture the inevitable interference from the non-faradaic charging current. Analyses show that nanoelectrodes should be preferred over planar electrodes to overcome this interference, as well as a highly mobile supporting ion system is required as an electrolyte to capture characterizable faradaic response. Since these energies have a universal presence in materials, the method is expected to be generally applicable in characterizing molecular and nanoparticle systems." --

Download or read book Design of Electronic Devices Using Redox Active Organic Molecules and Their Porous Coordination Networks written by Jaejun Kim and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the development of electronic devices using redox-active organic molecules and their porous coordination networks (PCNs), and highlights the importance of the molecular arrangement. Redox-active organic molecules hold considerable promise as flexible electronic elements, because their electronic state can easily be controlled using external energy. Although various kinds of redox-active organic molecules have been synthesized, attempts to apply them to electronic devices have been limited, owing to the lack of proper structural design. Moreover, ligand-based redox-active PCNs remain largely unexplored because of the limited availability of redox-active ligands. In addition to developing new redox-active organic molecules, in order to design electronic devices based on these molecules/PCNs, it is essential to understand the connections between their molecular arrangement, electrical properties, and redox activity. In this thesis, the redox-active organic molecule 2,5,8-tri(4-pyridyl)1,3-diazaphenalene (TPDAP), which features a large pi plane and multi-intermolecular interactivity, is used to develop a resistive switching memory device. In addition, its PCNs are synthesized to fabricate chemiresistive sensors, and the electrical properties are modulated using post-synthetic modification. Each mechanism is systematically investigated by means of structural determination and well-defined control experiments. Subsequently, the book proposes general guidelines for designing electronic devices using redox-active organic molecules. The book will appeal to a broad range of readers, from basic scientists to materials engineers, as well as general, non-expert readers. .
