摘　　要：场发射在扫描电子显微镜、平面显示器、压力传感器、加速度传感器以及电子束可寻址记忆器件等许多领域中得到了广泛的应用,分子基材料由于其结构和能带可设计,性质可调和柔性易加工等显著特点,被认为是新一代的场发射材料。本文综述了近年来分子基材料聚集态结构的场发射性质研究的新进展,特别是分子基材料的结构和聚集态形貌和尺寸对场发射性质的影响以及通过对分子基材料的杂化优化其场发射的性质,展望了分子基材料聚集态结构场发射的应用前景和发展趋势。Field emission has been widely used in many areas, such as scanning electron microscopy, plane display device, pressure sensor, acceleration sensor and electron beam addressed memory devices etc. Molecular materials are potential candidates for future field emission cathode materials, due to their notable characteristics of adjustable structures and energy bands, flexible nature, and easy processing. In this work, we will review some field emission properties of aggregation structure based molecular materials, especially, the effects of size and morphology based on field emission properties of molecular materials are described in detailed. The aim of review provides an intuition for understanding the structure-function relationships in molecular materials, which could lead to new design concepts for the development of new high field emission performance molecular materials on aggregate nanostructures.
