Synthesis And Opto-electronic Properties Of Two Organic Semiconductor Materials: Thiophene Compands And Organic-inorganic Hybrid Compands

Organic semiconductors are hot research subject, because they have great potential in applications such as organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), photovoltaic cells and so on. Compared to inorganic semiconductors, organic semiconductors are more easily synthesized and lower price to large-area manufacturing. The acene and thiophene oligomers because of their good performance and good stability under ambient condition, represent two of the most heavily studied series of compounds for use as OFETs.1.Thiophene derivatives, as one of the most important classes of conjugated compounds, have been the focus of a number of older and more recent reviews, due to its prospect applications in conducting films, electrochromics and field-effect transistors. In this dissertation, we designed pyridine and thiophene to synthesize 5,5'-Bis(3-pyridinyl)-2,2'-bithiophene,5,5'-Bis(3-quinolyl)-2,2'-bithiophene,5,5'-Bis(9-phe-nanthryl)-2,2'-bithioph,ene 8,8'-Bis(3-pyridinyl)-2,2'-terthiophene. We research the optical and electrical properties of 5,5'-Bis(3-pyridin-yl)-2,2'-bithiophene thiophene.2. In this dissertation, we designed pyridine and thiophene to synthesize (4-BrC6H4NH3) 2PbI4, (4-such as C6H4N) 2SnCl6. Through measuring we found these two kinds of crystals in the metal atoms are composed of an anionic octagonal center, and all kinds of hydrogen bonding improve the stability of the crystal.
