Abstract

Molecular gels are ubiquitous soft solids formed by the self-assembly of small building blocks via the weak intermolecular interactions resulting in the formation of 3D nano- or micro fibrous network wherein solvent molecules are trapped that act as an excellent platform for environmental and energy applications. Appropriate molecular modification can alter the nanoscale assembly which could be utilized practically for various applications in the field of biology, medicine, and materials science. The nanofiber formation in gel can be transformed into conducting architectures or metallic nanowires via doping and annealing procedure. Since gels are formed by weak intermolecular interactions, the gel-to-solution transition can be triggered by various external stimuli such as temperature, mechanical action, light, ultrasound waves, acids, bases, ions, redox reagents, and biomolecules. However, gel-to-sol phase change associated with stimuli-responsive behavior can be used for tuning the molecular-level behavior. This chapter reviews the various practical applications of molecular gels such as removal of dyes, aromatic compounds, toxic metals, anions, hydrocarbons, crude oil, smart photonics, electrolytes, and artificial light-harvesting devices.
