使用場效晶體管及發光二極管來製作井然有序介面之有機分子,開發井然有序的分子薄膜和納米結構高度依賴於有機分子的自序性[9],[23]。本論文採用超高真空低溫掃描隧道顯微鏡,研究了多環芳烴2,5,8,11,14,17-hexabromo hexabenzocoronene (Br6HBC) 和3,10-Bis(Bromo-Methyl) Phenacene (3,10 BMP)在金屬基材上的沉積、自組和形成。我們可以通過將多環芳烴分子蒸發到Au(111) 上來獲得化學結構和電子特性。Ag(111)上3,10個BMP分子的參數代表了各種自組。每種配置都表現出獨特的電氣特性,並具有額外的局部狀態。產生武茲反應在熱處理後在金屬表面上形成聚合物。
When using organic molecules in devices such as field-effect transistors and light-emitting diodes, well-ordered interfaces are required. Developing ordered molecular thin films and nanostructures highly depends on the self-ordering of organic molecules[9],[23]. This thesis studied the deposition, self-assembly, and network formation of 2,5,8,11,14,17-hexabromo hexabenzocoronene (Br6HBC) and 3,10-Bis(Bromo-Methyl)-[5]Phenacene (3,10 BMP) molecules on metallic substrates by using the ultrahigh-vacuum low-temperature scanning tunneling microscope.We can obtain the chemical structure and electronic properties by evaporating Br6HBC molecules onto the Au(111). The preparation parameter of 3,10 BMP molecules on Ag(111) represents the self-assembly of various kinds. Every configuration
exhibits unique electrical characteristics and has additional localized states. The well-known Wurtz coupling reaction is created to form polymers on a metal surface after thermal treatment.
