Abstract

The last 20 years have witnessed major advancements in the field of supramolecular chemistry and have brought us closer to the designing of low molecular weight gelators with desired properties and applications. In that regard, amide- and ureabased gelators comprise a unique class as they are extremely versatile in terms of molecular design and offer a wide range of applications, like anion responsive materials, selective sensing of heavy metal ions, environmental remediation and many more. Both sets of compounds have similar molecular scaffolds, making them an excellent tool to determine the relative importance of the supramolecular interactions involved in the gelation process. Besides, the concept of crystal engineering can also be employed to understand the underlying mechanism of gelation by scrutinizing the interactions and supramolecular assemblies formed by these systems. In this article, we focus on various supramolecular assemblies formed by various amide and urea derivatives and their recently reported applications to establish structure-property correlation and their futuristic aspects.

Keywords: Low molecular weight-gelators, crystal engineering, self-assembled fibrillar networks, structure-property correlation, SANS, nucleic acids.
