Naphthalimide-based fluorescent gelator for construction of both organogels and stimuli-responsive metallogels

Abstract

Herein, we presented the first example that a gelator can form both organogels and metallogels with multiple gelation approaches tuned by multiple stimuli.

Design and synthesis of hydrophobic mixed organogels with complementary hydrogen-bond donor–acceptor sites: removal of heavy metal ions Hg2+, Cd2+ and Pb2+ from aqueous solution

“…Interestingly in these cases, the strength of the gel was found to be decreased with the incorporation of metal ions, which is the reverse of the general trend. 53,54 It signifies that the non-covalent interactions between G8 and GE molecules are disturbed by the insertion of metal salts with mixing. To overcome this disturbance, we have taken the unique approach of allowing the metal ions to diffuse through the bulk gel materials in a layering technique, revealing the increased storage modulus of metallogels compared to the organogel and mixed metallogels.…”

“…Basically non-covalent interactions like hydrogen bonding, p-p stacking, intra-or intercolumnar stacking, van der Waals, hydrophobic and hydrophilic interactions and dipole-dipole interactions are the important reasons behind gel formation. [7][8][9] These forces generally operate between different molecules and, because of their weak nature, easily get affected by external stimuli like heat, 10,11 light, 12,13 pH, 14,15 etc. The associated changes of these effects in the physical properties of the gels can be observed sometimes by the naked eye or otherwise can be recorded through different instrumentation techniques.…”
