Abstract

Abstract The synthesis of four bis (trialkoxysilylated) organic molecules capable of self- assembly—(EtO) 3 Si (CH 2) 3 NHCONH [BOND](CH 2) n [BOND] NHCONH (CH 2) 3 Si (OEt) 3 (n= 9–12)—associating urea functional groups and alkylidene chains of variable length is described. These compounds behave as organogelators, forming supramolecular assemblies thanks to the intermolecular hydrogen bonding of urea groups. Whereas ...
