Book Description
Semiconducting polymers are of great interest for applications in electroluminescent devices, solar cells, batteries, and diodes. This volume provides a thorough introduction to the basic concepts of the photophysics of semiconducting polymers as well as a description of the principal polymerization methods for luminescent polymers. Divided into two main sections, the book first introduces the advances made in polymer synthesis and then goes on to focus on the photophysics aspects, also exploring how new advances in the area of controlled syntheses of semiconducting polymers are applied. An understanding of the photophysics process in this kind of material requires some knowledge of many different terms in this field, so a chapter on the basic concepts is included. The process that occurs in semiconducting polymers spans time scales that are unimaginably fast, sometimes less than a picosecond. To appreciate this extraordinary scale, it is necessary to learn a range of vocabularies and concepts that stretch from the basic concepts of photophysics to modern applications, such as electroluminescent devices, solar cells, batteries, and diodes. This book provides a starting point for a broadly based understanding of photophysics concepts applied in understanding semiconducting polymers, incorporating critical ideas from across the scientific spectrum.

Book Description
Conjugated polymers have been the focus of intense research for more than a decade now, and advances in this field are beginning to materialize in the production of high-efficiency opto-electronic materials that may led to the generation of energy without the need for fossil fuels. However, these current materials have not been shown to be capable of reaching efficiency levels high enough to be competitive with the silicon-based solar cells that are the standard today. We embarked on a journey in this work to help the next step in conjugated polymer research be attained. We have done just that through a fundamental study of dilution solution properties of these materials in addition to the synthetic pathway we have cleared so that highly functionalized conjugated polymers may be synthesized that will lead to block copolymers with tailored properties. These materials will revolutionize the field of organic photovoltaics and organic field transistors. The synthetic method for the generation of functionalized conjugated polymers described here represents an approach that can used to impart any number of functionalities onto the conjugated polymer chains which will lead directly to block copolymer systems. We have shown this ability through the synthesis of a diblock copolymer with promise of a miktoarm star block copolymer in this work. The versatility of the method developed here allows for other combinations of polymers and molecular architectures to be attainable in like manner. This work serves to provide other means by which these useful polymers may reach their maximum potential.

Book Description
This digital primer serves as an excellent introduction to conjugated polymers, particularly in terms of their synthesis and design. Chapters one and two introduce common terminology and fundamental concepts. Chapter three covers known structure–function relationships that can be used to design conjugated polymers with the desired properties for specific applications, concluding with a discussion of the additive and sometimes conflicting aspects of these design elements. Chapters four, five, and six cover the various methods used to synthesize these materials, beginning with the oldest and most simple approaches, and increasing in synthetic complexity. Advanced undergraduates, graduate students, and faculty wishing to enter this field for the first time should find this primer beneficial. At the same time, however, we have pointed out various misconceptions still commonly found in the literature, which should be valuable to those already familiar with these materials.

Book Description
Solar energy harvested directly from sunlight using photovoltaic (PV) technology has become one of the most promising ways to meet growing global energy needs with a sustainable resource while minimizing environmental concerns. Especially, organic bulk heterojunction (BHJ) solar cells have been attracting a great deal of interest as a source of renewable energy because of their potential as low-cost, flexible, light-weight and large-scale devices. The choice of materials in a BHJ solar cell is very important for device performance because the power conversion efficiencies (PCEs) are determined by their some crucial characteristics such as energy levels, charge transfer mobilities and structural orders. In this dissertation, two carbazole-diketopyrrolopyrrole based conjugated polymers (P1 and P2) and three thieno-[3,4-c]pyrrole-4,6-dione (TPD) based small molecules (M1, SM1 and SM2) were synthesized and characterized to investigate their optical, electrical and photovoltaic properties. First, the substitution of alkyl and aryl side chains on the carbazole moiety of two push-pull conjugated polymers (P1 and P2) shows the significant differences in the optical, electrical and photovoltaic properties. Second, TPD-based conjugated small molecule with a donor-acceptor-donor-acceptor-donor (D-A-D-A-D) framework, M1 shows the relatively deep HOMO level resulting the relatively high Voc.(0.85 eV) Small molecule BHJ solar cells were fabricated and characterized using different M1:PC71BM blend ratios, solvents, and additives and the highest PCE achieved in this study was 1.86%. Lastly, different bridgehead atoms of SM1 and SM2 can affect their energy band levels and device performances. The PCE (2.5%) of the SM2-based SM-BHJ solar cell was higher than that of the SM1-based SM-BHJ solar cell (1.5%).
