Organogelators based on iodo 1,2,3-triazole functionalized with coumarin: properties and gelator-solvent interaction

Gel scaffolds and emerging applications in biomedicine

“…23a ). 79 A new kind of coumarin-based photoresponsive hydrogelator DPC (56) can self-assemble into nanofibrous structures in an aqueous solution. The resulting DPC hydrogel can be disintegrated due to the photomediated cleavage of the DPC gelators under UV light irradiation, resulting in the precise and efficient release of encapsulated agents.…”

Synthesis and characterization of amide linked triazolyl glycolipids as molecular hydrogelators and organogelators

“…Recently we and others have reported several triazole based low molecular weight gelators. [50][51][52][53][54][55][56] Certain peracetylated D-glucosyl triazoles and D-glucosamine triazole analogues (2 and 3) are found to be effective gelators and they are able to gelate alcohols, DMSO and water mixtures, ethanol and water mixtures, a few analogs are also effective gelator for water. 52,53 The glucosyl triazole derivatives 2 are more effective organogelators.…”

Photoresponsive gelators

“…A small number of coumarin-based LMWG have been reported. [105][106][107][108][109][110][111] Parquette and co-workers designed a coumarin dipeptide hydrogelator containing two coumarin groups connected by a dipeptide. 106 The two coumarin groups allowed each gelator to react with two other gelator molecules to increase the amount of cross-linking upon irradiation.…”
