Recognition of hydrophilic amino and N,N-dimethylamino compounds by the self-assembled aggregates of fluoroalkylated end-capped N-(1,1-dimethyl-3-oxobutyl)acrylamide oligomer

Self-assembled aggregates of new fluoroalkylated end-capped N-(1,1-dimethyl -3-oxobutyl)acrylamide oligomer can recognize selectively hydrophilic amino and N,N-dimethylamino compounds such as methylene blue, methyl orange, acr iflavine hydrochloride and S-amino-phenylboronic acid, and transfer these c ompounds from aqueous solutions to organic media; in contrast, these aggreg ates were not able to recognize hydrophilic compounds such as 4-hydroxyazob enzene-4'-sulfonic acid sodium salt, acridine hydrochloride, 4-methoxypheny lboronic acid, 4-methyl-3-nitrophenylboronic acid, and phenylboronic acid.
