Abstract

In recent times, porous nanomaterials have attracted a lot of attention from researchers worldwide and have been targets for both academic and industrial researchers. Metal Organic Frameworks (MOFs), Covalent Organic Frameworks (COFs), zeolites, graphene, MXenes, molecular cages, and carbon nanotubes (CNTs) are some of the well-known examples of the porous nanomaterials. Their unique structures, properties, and potential applications in various areas have led to this fame and exposure. Among these, CNTs hold a special place of attraction among researchers due to their excellent mechanical and electronic properties. However, one crucial drawback is the harsh reaction conditions required for their synthesis and the inability to modify their backbone. There have been multiple efforts to find organic equivalents of CNTs, and supramolecular self-assemblies have led to the formation of nanotubular structures, but they lack control over size, composition, and morphology. Here we report an easier, more eco-friendly synthesis of a covalent organic nanotube (CONT) which is an extension of the work reported by Koner et al. in 2022. This work shows an isoreticulation of CONTs and synthesis of new linkers for future CONTs.
