摘要

Organic semiconductors are designed and synthesized on the basis of building blocks. Presented in this thesis are studies on using unconventional building blocks, namely cyclopentadiene, cycloheptatriene and butatriene, to construct new organic semiconductors. Chapter 1 first briefly introduces organic electronics with focus on the device structure and working principles of organic thin film transistors (OTFTs) and organic photovoltaic cells (OPVs), and then reviews small-molecule organic semiconductors for OTFTs highlighting building blocks. Chapter 2 presents a study on a new group of cyclopent[hi]aceanthrylene derivatives, which have two cyclopentadiene moieties to accept electrons and are thus applied as ambipolar organic semiconductors in OTFTs and as acceptors in OPVs. Chapter 3 introduces a bifunctional hydrocarbon, which has two non-planar dibenzocycloheptatriene moieties linked by three cumulative C--C double bonds. Of particular interest is that the molecule's solids not only function as p-type semiconductors but also exhibit vapochromic behavior with high selectivity. Chapter 4 demonstrates v tetraarylbutatrienes as a general design for organic semiconductors detailing a comprehensive study on the synthesis, electronic structures, molecular packing, semiconductor properties and solid-state reactivities.
