Abstract:

Organogel networks from low molecular weight components are a fascinating class of functional nanomaterials, with tremendous potential for a wide variety of commercial applications ranging from medicine, electronics, printing, personal care, and environmental remediation [1]. Here, we discuss the synthesis and characterization of nanostructured organogels from two new classes of amphiphilic compounds: (1) alkylated isophthalic acids (ISA) and (2) alkylated benzimidazolones (BZI). Both classes exhibit excellent gelator behavior in a variety of nonpolar solvents due to the formation of robust 3D networks of well-defined nanostructured aggregates stabilized by hydrogen-bonding, pi-stacking, and van der Waals interactions.
