Self-assembled dendron nanotubes: Surface functionalization with maltosyl units and their reversible complexation with concanavalin A

A study was conducted to demonstrate the conjugation of a carbohydrate moiety, maltosyl unit onto the surface of Den-CD-NT to investigate the carbohydrate protein interaction on the nanotube surface. A novel approach was proposed to construct maltosyl functionalized Den-CD-NTs with a multivalent capability and their specific recognition processes with Concanavalin A (Con A). 1,10-Carbonyldiimidazole (CDI), lauric acid, 1-pyrenecarboxylic acid, 1-pyrenebutyric acid, 1-aminopyrene, 1,3-dicyclohexylcarbodiimide (DCC), 1,3-diisopropylcarbodiimide (DIPC), 4-(dimethylamino)pyridine (DMAP), N-hydroxysuccinimide, ethylenediamine, and 8-anilinonaphthalene-1-sulfonate (ANS) were used to conduct the investigations. These were purified by vacuum distillation under calcium hydride, while succinic anhydride was recrystallized from n-hexane and acetone.
