Available in PDF, EPUB and Kindle. Book excerpt: A description of how semiconducting fluorescent polymers function as chemosensors for a variety of chemical vapors is presented. Amplification is achieved by transport of optically induced excitations throughout a polymer film. Careful and thoughtful design of polymer chemical structures is crucial to achieving high sensitivity towards nitroaromatic explosives such as trinitrotoluene (TNT) and dinitrotoluene (DNT). These semiconductive materials have been incorporated into functional sensory devices used for ultratrace explosive detection in the search for hidden landmines. Research efforts in our group have been aimed improving the sensitivity, selectivity, and versatility of conjugated polymer sensors through rational molecularly design.

This book was released on 2021 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conjugated polymers, representing a new generation of semiconductors, have attracted tremendous attention in the past few decades attributed to their conspicuous properties, such as flexibility, light weight, stretchability and solution processability, which is promising for manufacturing low-cost, large-area, and flexible electronic devices. Moreover, performance of semiconducting behaviors could be readily modulated via manipulating chemical structure and morphology. Organic field-effect transistors (OFETs) are the elemental components in electrical circuits. Although considerable materials were synthesized and investigated, there are still numerous approaches either in novel materials or morphological control which have not been explored. Therefore, in this research, five different strategies were proposed to attain conjugated polymer-based higher performance materials for OFETs, including novel pigment monomers, polymerization method and morphological manipulation by hydrogen bonding and conjugated cross-linking. In Part I, a blue/violet pigment, benzimidazolone-dioxazine-based molecule, was employed into donor−acceptor based conjugated polymers. Through the molecular modulation, the donors with matched size for donor-acceptor packing in the conjugated polymer thin films were uncovered, revealing refined charge carrier mobilities owing to the extended conjugated length of benzimidazolone-dioxazine structure. Part II discloses the diketopyrrolopyrrole(DPP)-quaterthiophene-based donor-acceptor copolymers with latent hydrogen bonding isoindigo-bithiophene to amend the charge transport in amorphous phase via hydrogen bonding-induced aggregation after thermal treatment. Part III applied the robust hydrogen bonding interaction to directly patterning conjugated polymer thin films and their OFETs with exceptional balance of mobilities and resolution of patterns, which is compatible with conventional photolithography in integrated circuit. Part IV introduces a newfangled method to obtain conjugated polymers with controlled molecular weight in the solid state, consisting of conventional anionic-polymerization and topochemical reaction. Moreover, this strategy could be further utilized to prepare the high-performance semiconducting material, graphene nanoribbons. Part V coalesced the concepts of Part II and IV to construct conjugated cross-linking between polymer backbones through topochemical reactions on diketopyrrolopyrrole(DPP)-quaterthiophene-based copolymers with latent cross-linkable diacetylene-bithiophene moieties, ameliorating the charge transport without demolishing the favorable packing of donor-acceptor conjugated polymers.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The relative placement of side chains along the backbone has a great influence on the solid state ordering of conjugated polymers. Poly(2,5-disubstituted-1,4-phenylene ethynylene)s (PPE)s, an important class of conjugated polymers, are generally synthesized by Pd-catalyzed coupling polymerizations of appropriately substituted diiodo and diethynyl benzenes (i.e., A-A and B-B type monomers). In asymmetrically substituted PPEs, this results in an irregular substitution pattern of the side chains along the polymer backbone. We report a new synthetic approach to prepare regioregular unsymmetrically substituted PPEs by polymerization of 4-iodophenylacetylenes (i.e., A-B type monomer). We provide a detailed discussion of various approaches to the synthesis of PPEs with different regioregularities and provide a description of the differences between regioregular and regiorandom analogs.

Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this dissertation focuses on the design and synthesis of novel hybrid conjugated polymer materials using two different approaches: 1) inorganic/organic hybrid semiconductors through the incorporation of carboranes into the polymer structure and 2) the modification of surfaces with conjugated polymers via grafting approaches. Hybrid conjugated polymeric materials, which are materials or systems in which conjugated polymers are chemically integrated with non-traditional structures or surfaces, have the potential to harness useful properties from both components of the material to help overcome hurdles in their practical realization in polymer-based devices. This work is centered around the synthetic challenges of creating new hybrid conjugated systems and their potential for advancing the field of polymer-based electronics through both greater understanding of the behavior of hybrid systems, and access to improved performance and new applications. Chapter 1 highlights the potential applications and advantages for these hybrid systems, and provides some historical perspective, along with relevant background materials, to illustrate the rationale behind this work. Chapter 2 explores the synthesis of poly(fluorene)s with pendant carborane cages. The Ni(0) dehalogenative polymerization of a dibromofluorene with pendant carborane cages tethered to the bridging 9-position produced hybrid polymers produced polymers which combined the useful emissive characteristics of poly(fluorene) with the thermal and chemical stability of carborane cages. The materials were found to display increased glass transition temperatures and showed improved emission color stability after annealing at high temperatures relative to the non-hybrid polymer. The design and synthesis of a poly(fluorene)-based hybrid material with carborane cages in the backbone, rather than as pendant groups, begins in chapter 3. Poly(fluorene) with p-carborane in the backbone is synthesized and characterized, and the material is found to be a high MW, soluble blue emitter which shows a higher glass transition temperature and greater stability than a non-hybrid polymer. UV absorbance and fluorescence spectroscopy indicated some electronic interaction between the conjugated polymer and the cages, but they did not appear to be fully conjugated in the traditional sense. Chapter 4 describes the design, synthesis, and characterization of poly(fluorene) with o-carborane in the backbone. Profound changes in the behavior of the polymer, from its polymerization behavior to its emission characteristics, were observed and their origins are discussed. Experiments to explore the nature of the cage/polymer interactions were performed and possible applications which take advantage of the unique nature of the o-carborane hybrid polymer are explored and discussed. Hybrid conjugated polymer materials via grafting approaches to surfaces and surface modification are discussed starting in chapter 5. The synthesis of a dibromofluorene-based silane coupling agent for the surface functionalization of oxide surfaces is presented, and the surface directed Ni(0) dehalogenative polymerization of poly(dihexylfluorene) is explored Chapter 6 focuses on the exploration of conjugated polymer/cellulose hybrid materials. Surface medication of cellulose materials with monomer-like anchor points is discussed. Grafting of the modified cellulose with conjugated polymers was explored and the grafting of three different repeat structures based on fluorene-, fluorenevinylene-, and fluoreneethynylene motifs were optimized to provide a general route to cellulose/conjugated polymer hybrid materials. Characterization and possible applications of such hybrid materials are discussed. Finally, chapter 7 is devoted to the simultaneous surface patterning and functionalization of poly(2-hydroxyethylmethacrylate) thin films using a silane infusion-based wrinkling technique. While not a conjugated polymer system, the spontaneous patterning and functionalization methods explored in this chapter produce hybrid organic/inorganic polymer thin films which have applications that range from optics, to adhesion, to polymer-based electronics, and the research compliments the other chapters. The spontaneous generation of complex patterns, of a small scale approaching 100nm feature size, over a large area with simultaneous control over surface chemistry is explored. Examples of complex, hierarchically patterned films which integrate lithographic processes such as nanoimprint lithography and electron beam lithography with spontaneous patterning via wrinkling are presented.
