【摘要】 本论文围绕有机半导体材料的合成与器件应用开展。首先研究了在氮杂并苯类分子的合成与器件制备；在此基础上,将工作拓展到氮杂石墨烯及类似物的合成与表征,探讨了其在荧光标记与催化领域的应用。主要研究内容包括：1.在本组前期研究成果的基础上,设计并合成了一系列氮杂并苯衍生物,意在研究其电学性质(场效应迁移率)。由于分子热稳定性很差,无法通过常规方法进行真空镀膜,探索了溶液法制备有机薄膜的技术。2.将石墨烯材料制备成独立式的纸电极,将其作为MoS2的支撑材料,利用溶剂热法在其表面修饰MoS2,研究其在催化产氢方面的性能。同时,将三辛基磷(TOP)作为表面活性剂,对MoS2的形貌进行调控,比较不同形貌下催化活性的高低。更多还原

【Abstract】 Organic acenes, composing of sp2carbon atoms, have attracted increasing attentions because of its cheapness and impressive performance. In recent years, it is found that the stacking mode can be modulated by introducing substituents into the skeleton of acenes, enhancing π-π interaction, resulting in increase of mobilities. The HOMO and LUMO level can also be lowered down by importing nitrogen atoms, improving the stability of the molecules.The first part of the thesis focuses on the design and synthesis a series of N-heteroacene derivatives. The aim is to study the electrical properties, ie. field effect mobility. Because vacuum coating cannot be carried out due to the poor thermal stability of the molecules, solution process for organic thin film was explored for these materials.Molybdenum disulphide (MoS2), possesses lamellar structure similar to graphene. It has been considered as an excellent catalyst for hydrogen evolution reaction (HER). Under the optimal morphology, the catalytic performance is comparable to that of platinum catalyst. At the same time, trioctylphosphine (TOP) was used as the surfactant to control the morphology to compare the catalytic performance under different morphology.更多还原
