要旨

Covalent organic frameworks (COFs) are a class of porous materials generated from organic molecules resulting in two-dimensional (2D) or three-dimensional (3D) networks. Multifunctional molecules with defined symmetry react to give all-linked-COFs with pre-determined topologies. COFs and COF-based materials have continuously evolved via the exploration of new linkages, synthesis, and processing methodologies over nearly two decades. Several studies have contributed to the understanding of the formation mechanism and the influence of solvent(s), catalysts, and the reaction environment in the crystallization process. Apart from all-linked COFs with a “fully formed” network, sub-stoichiometric synthesis has been a recent development, where the change in stoichiometry of monomers results in generating unconventional topologies along with active functional groups within the pores of these materials. Thus, the generation and utilization of these “functional” COFs is an interesting challenge for reticular chemists, particularly in terms of the vast possibilities of applications that are not likely to emerge from conventional synthesis.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
