Triptycene-derived Metal-Organic Frameworks: Unusual Topologies, Connectivites and Physical Properties

摘要

Research of two-dimensional (2D) semiconductive metal-organic frameworks (MOFs) has become an attractive topic for coordination chemists and material scientists, as these materials intrinsically combine two important features: porosity and conductivity together within a sole material. Hence, various applications, such as electrocatalysis, FET devices, chemiresistive sensors and supercapacitors have be pursued for these materials. Although outstanding performances have been achieved with these 2-D MOFs, it is difficult to further tune their structures and properties. With a rigid planar structure, triphenylene derivative ligands tend to create two-dimensional layered graphene analogue structures with strong π-π interactions and leave little space for chemists to introduce any manipulation.
