Recognition properties of naphthalenediimide organogel

In this presentation we would discuss about a newly designed and synthesized naphthalenediimide-based organogel (1) and its facile recognition properties with dihydroxynaphthalenes (Figure 1). This organogel is stabilized by a multiple set of non-covalent interactions like π-π stacking, H-bonding and van der Waals interactions. These supramolecular interactions confer a host-like character to the gel matrix and by virtue of which it can differentiate the different classes of electron rich naphthalene compounds like, dihydroxynaphthalenes from alkoxy, alkyl and monohydroxynaphthalenes. Naked eye demarcation of several positional isomers of dihydroxynaphthalene becomes possible within the gel matrix due to a coerced H-bonding driven recognition.
