Schiff base network1 (SNW1) is a recently synthesized covalent organic framework (COF) that has garnered significant interest in the field of materials science and chemistry. It is synthesized through the condensation reaction of melamine with terephthaldehyde and has abundance of imine functional groups present within its chemical structure. Due to its distinctive characteristics such as elevated specific surface area, exceptional thermal and chemical durability, simple synthesis process, and notable electrochemical conductivity, numerous investigations have been conducted on this COF across diverse analytical chemistry domains. Our research group also explored the applications of this COF and its composites in different fields like microextraction methods, adsorptive removal of environmental contaminants, and electrochemical sensing of heavy metals. In this respect, we decided to introduce SNW1 COF in this short review and have a detailed discussion on its chemistry, and its scrutinized applications in analytical chemistry. Additionally, the literature that has been analyzed yielded pivotal insights, and a set of suggestions have been formulated for subsequent scholarly pursuits.
