Available in PDF, EPUB and Kindle. Book excerpt: Organic semiconductors are potential candidates for replacing high-cost silicon electronics for low-end applications where high mobilities are not required. Owing to unique advantages such as solution processability, flexibility, lightweight, low cost with countless structural modifications, organic semiconductors can be realized for many applications using high throughput roll-to-roll fabrication techniques. Hence, a remarkable amount of scientific efforts have been dedicated to improving electronic and physical properties of these materials. Throughout the past two decades, many improvements in the field have been achieved by designing novel building blocks. Since efficiencies and mobilities in organic solar cells and transistors have stagnated, it is highly desirable to seek and develop non-conventional building blocks for organic electronics. In this dissertation, the fundamentals and recent developments of non-conventional materials are covered in Chapter 1. Operation principles, charge transport of organic field effect transistors and organic photovoltaics are introduced. Compared to conventional thiophene-based -electron donor materials, promising non-conventional pyrrole based donor materials employed in organic electronics are discussed and summarized. Similarly, non-conventional electron acceptors could be used to fabricate organic solar cells. By using inorganic semiconducting quantum dots (QDs), organic-inorganic hybrid solar cells could be fabricated. Different systems with polymer: QD solar cells are also discussed and summarized in chapter 1. Chapter 2 describes the effect on organic field effect transistor (OFET) properties of two novel small molecules containing terminal N-dodecylthieno[3,2-b]pyrrole (TP) donors and N-dodecylfuro[3,2-b]pyrrole (FP) donors with a central thiophene flanked 5,6-difluorobenzo[c][1,2,5]thiadiazole (FBT) acceptor. The influence on frontier molecular orbital energy levels, UV-vis absorption, electrochemical properties, OFET parameters and morphological effects were investigated. In chapter 3, the effect of flanking group on banana shape small molecules is discussed by using terminal N-dodecylthieno[3,2-b]pyrrole (TP) donors, and thiophene or furan flanked benzo[c][1,2,5]thiadiazole (BT) central units. Upon changing similar flanking groups, the curvature of the small molecules was changed. Thiophene flanked small molecule showed high hole mobility of 0.08 cm2 /V s while furan flanked small molecule performs poorly due to both heteroatom effect and the degree of curvature. Chapter 4 describes the extension of thieno[3,2-b]pyrrole based small molecules to polymers. A Novel conjugated polymer is synthesized by copolymerizing N-methylthieno[3,2-b]pyrrole and 2,5-bis(2-octyldodecyl)-3,6-di(thiophen-2-yl)-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione (DPP) via Stille coupling polymerization. With an optimized molecular weight, the polymer exhibited high hole mobility of 0.12 cm2 /V s in OFET devices. The high hole mobility reflects the potential of the thieno[3,2-b]pyrrole building block. Inorganic QDs also can be employed as electron acceptors compared to conventional fullerene derivatives in bulk heterojunction (BHJ) solar cells. However, they do not outperform conventional fullerene counterparts. Therefore in chapter 5, a facile method is described to generate thiol functionalized block copolymers to improve the interaction between photoactive polymers and QDs. By incorporating only 17 mol% of the thiol containing block a two-fold increase in power conversion efficiency was observed. The improved interaction was supported by atomic force microscopy and photoluminescence quenching studies.

Download or read book Development of New Building Blocks for Constructing Novel Polymer Semiconductors for Organic Thin Film Transistors written by Zhuangqing Yan and published by . This book was released on 2013 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic semiconductors are envisioned to have widespread applications in flexible displays, radio-frequency identification (RFID) tags, bio- and chem-sensors, as well as organic solar cells. Polymer semiconductors are particularly suitable for the low-cost manufacture of organic electronics using printing techniques due to their excellent solution processability and mechanical properties. This work focuses on the development of two novel building blocks, IBDF and DTA, which can be used for the construction of high performance organic thin film transistors (OTFTs) and organic photovoltaics (OPVs). Two copolymers, P6-IBDF-T and P5-IBDF-T, and a homopolymer P6-IBDF were prepared using the IBDF building block. Copolymer P6-IBDF-T has been prepared via the Stille-coupling polymerization. This polymer exhibits a small band gap of 1.36 eV with HOMO/LUMO energy level of -5.69 eV/-4.43 eV. P6-IBDF-T showed stable electron transport performance in encapsulated thin film transistors and ambipolar transport performance in non-encapsulated TFTs. Balanced hole/electron mobilities of up to 8.2 ×10-3/1.0 ×10-2 cm2V-1s-1 was achieved in bottom-contact, bottom-gate organic thin film transistors. In addition, the broad absorption of the polymer over the UV-Vis range suggested that this polymer is suitable for applications in solar cells. The effect of conjugation on mobility and UV-vis spectra of the polymer was studied by comparing P5-IBDF-T with P6-IBDF-T. The ideal of indirect electron transition was proposed to explain the difference between UV-Vis light absorption spectra for these two polymers. DTA building block was used to construct four D-A copolymers, namely PDTA-T, PDTA-BT, PDAT-BTV, and PDTA-TT. These polymers were characterized by UV-Vis, CV, DSC, TGA, AFM and XRD. Device performance was also investigated on OTFTs. The device performance of DTA based polymer increased as the area of electron donor increase from T in PDTA-T to BTV in PDTA-BTV. PDTA-BTV exhibits hole mobility of 1.3×10-3 cm2 V-1 s-1 with Ion/Ioff value of ~103-4 in bottom-contact, bottom-gate organic thin film transistors. All DTA based copolymers exhibited small optical bandgaps (1.18 - 1.27 eV) and required none or moderate thermal treatment during fabrication process. These make them promising candidates for cost-effective OPV applications.
