Development of supramolecular organo-gel based on tripeptide skeletons

Boc-Ser-Val-Gly-OCH(2)Ph (31) showed high gelation abilities in the aromatic solvents, particularly in toluene. The minimum gelation concentration of 31 in toluene was 10 mg/ml, suggesting that 2500 molecules of toluene were immobilized by each molecule of the tripeptide 31. The FT-IR data indicated that formation of antiparallel beta-sheets through intermolecular hydrogen bonding was central to the generation of nanofibers during gelation.
