Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Chemistry Conjugated conducting polymers are among some of the most versatile materials to emerge in the past 20 years. They have been researched for applications that range from photovoltaics, to light-emitting diodes, electrochromic windows, actuators, and field effect transistors. This work details the analytical characterization of [pi]-conjugated polymers to understand their redox and optical properties, along with the development of several new types of devices that employ these polymers as the active materials for both variable optical attenuators and as dual electrochromic/electroluminescent displays. Within this work, a phenomenon that we term unsymmetrical switching has been uncovered for the first time in reflective electrochromic cells. The unsymmetrical switching in these displays is explored and a model devised to illustrate that the presence of a conductive front propagating through the polymer film on electrochemical oxidation is the contributing cause for this observation. For these experiments, a variety of analytical techniques have been utilized to characterize the devices and materials contained therein and include electrochemistry, spectroelectrochemistry, and photometry.

Download or read book Pi conjugated Polymers for Electrochromic and Photovoltaic Applications written by Tanmoy Dey and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochromism is a process by which a material can change its electronic-optical properties upon charge injection/removal. Conjugated polymers are an interesting class of electrochromic materials because of their color tunability, high optical contrasts, fast switching speeds, and processability. Poly(3,4-propylenedioxy)thiophenes (PProDOT) are a substantial subclass of materials in conjugated polymer electrochromics due to their high optical contract between the bleached and colored states. Common derivatives of this molecule are typically made at the beta position with respect to oxygen on the seven membered ring. PProDOTs with methyl and benzyl substituents (beta position with respect to oxygen) are two of the more successful due to their high contrast. We have found that there is a much more substantial effect when PProDOT is derivatized in the positions alpha to the oxygen. For example, two t-butyl groups with each placed alpha to the oxygen in PProDOT incurs a 200 nm shift in the lambda max (365 nm) compared to having two methyl groups with each placed alpha to the oxygen. The dimethyl derivative is blue in color whereas the di-t-butyl, dihexyl, diisopropyl is showing yellow, orange and red color respectively. The polymer of this new derivative, P13ProDOT-TB2 and P13ProDOT-Hex 2 is organic-soluble and can be processed by a variety of solution methods, including spray coating. Furthermore we have also studied some selenium based polymer for electrochromic application. Poly(3,4-propylenedioxy)selenophenes (PProDOS) is showing better optical contrast, stability and faster switching speed as compared to their sulfur analogs. Low band gap conducting polymers (CPs) have relatively low absorption in the visible region, in their conducting states, making them promising candidates for optically transparent electrode, hole-injection layer for light-emitting diodes and suitable donor material for Photovoltaics. The monomer, Seleno[3,2- c]thiophene and Seleno[3,4-b]thiophene, were electrochemically and polymerized to produce new low band gap conducting polymer, poly(Seleno[3,2- c]thiophene) (PS32cT) and Poly(Seleno[3,4-b]thiophene) (PS34bT), having a low band gap of 1.03 eV and 1.50 eV respectively. Besides from the suitable energy gap, they also offer a good match of the absolute energy levels with the other materials in the photovoltaic device. The HOMO of the low band gap polymers agree with the work function of ITO and LUMO matches with the acceptor level of PCBM. This overlap is very important to the function of photovoltaic devices. In a different approach we describe a new alternative route for the synthesis of thieno[3,4-b]thiophene, alkyl derivatives thereof, seleno[3,4- b]thiophene, and thieno[3,4-b]furan made from inexpensive starting materials, such as thiophene-2-carboxylic acid and furan-2-carboxylic acid. Such fused heterocycles are of great interest for low band gap organic semiconductors and applications including OLEDs, organic photovoltaic cells, and electrochromic applications.

This book was released on 2015 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: While much research in the field of conducting polymers and organic electronics focuses on development of novel polymers and other related materials, or enhancing the properties of existing materials and understanding the mechanisms behind them, in many cases, clear and reliable future directions or applications of the research are unclear. Developing an understanding of the roles of different physical and chemical mechanisms and establishing simple, cheap and reliable manufacturing and processing technologies for conducting polymers will be crucial to guide future research to uncover modern materials for advanced practical applications. In the present work, several novel manufacturing and processing routes have been established to firstly create organic materials with desired properties and, later, to apply them in functional devices. Several adjustments have been made to the synthesis of conducting polymers, and novel ways for patterning of thin organic films developed, so that high-quality materials can be made cheaply and relatively quickly and then used to create functional devices with improved properties. Conducting polymers such as polyacetylene, polythiophene, polyaniline or poly(3,4-ethylenedioxythiophene) have been studied for several decades now; however, their properties have not been sufficient for widespread commercial application. Only recently have developments in the field and improvements in the properties of these materials, as well as better understanding of mechanisms underlying their functionality, allowed their use in prototype devices. The conductivity of organic materials is still relatively low compared to that of their inorganic counterparts, although some applications do not require such high electrical properties. A critical step was to better understand conductivity mechanisms and improve them using several different methods. Examples of methods to improve properties include blending two or more conducting or non-conducting polymers, co-polymerizing different monomers together or designing polymers and their surfaces on the nano-level. This work presents a study of two conducting polymers: poly(3,4-ethylenedioxythiophene) and poly(thiophene) and some attempts to increase their current properties or develop new properties to meet requirements for specific applications. Most of the effort focuses on the development of properties that are important for application in fields like energy production and storage, photonics and electronics. These critical properties include high electrical performance and high conductivity, good electrochemical properties, high surface area, broad light absorption spectra, biocompatibility, good mechanical properties and long lifetime. Chapter 3 discusses vapor phase co-polymerization of bithiophene and terthiophene as a route to widen absorption spectra of polythiophene materials. Chapter 4 describes processes responsible for formation of polythiophene nano-structures during vapor phase polymerization. It also explains conditions and polymerization parameters responsible for formation of different nano-structures so that those materials can be tuned for desired applications. Chapter 5 shows development of a laser ablation technique as a way to pattern conducting polymers to get the shape and architecture required for a specific device or application. The laser ablation technique is applied to manufacture organic electrochemical transistors and gas sensors. Lastly, Chapter 6 builds on knowledge from previous chapters to develop organic light sensors and opto-logic gates that can be used in an optical-to-electronic interface. This work significantly advances the state of knowledge of conducting polymers within the organic electronics field, and gives insights into how those materials interact with each other and how to tailor their properties. The findings here can serve as a basis for developing new conducting polymers, as well as direct investigations for new applications using the materials presented here.
