Two- and Three-Dimensional Network Structures from Design to Application

Abstract

From designing a molecular structure to the realization of the structure, the greatest challenge in chemistry is assembling molecules in a specific orientation and with a precise spatial arrangement. Depending on architectures, it is flexible what geometry, size and functional groups of building blocks are composed of and result from controllable chemical/physical properties. For example, the electronic device performance relied on material’s properties. Therefore, the material properties are indispensable to maximize status of devices. Graphene has spotlighted since discovery in 2004 due to outstanding physical properties over metal, even though composed of carbon. Inspired by graphene and graphene studies, graphitic 2-dimensional and 3-dimensional materials were prepared. Approached bottom-up process, graphene with heteroatom doping was prepared and succeeded tuning the bandgap and electrocatalytic effect increased. Moreover, graphitic carbon sheets with well-aligned carbon atoms with random-hole showed microporosity with relatively high surface area. The formation of organic-molecule-based superstructures was realized by solid-state conversion of an organic single-crystal. The resultant porous organic framework with 1-dimensional channels showed unusually high thermal stability tolerance to electron-beams. These prepared materials were analyzed the structure thoroughly and applied in energy conversion and storage system, etc.
