Dimeric sugar-based amphiphiles were synthesized starting from D-glucose and a commercial mixture of dodecyl and tetradecyl alcohols by a simple procedure. Three different spacers (glutaryl, succinyl and terephthaloyl) were used to link the sugar moieties through O-2 or O-6. Dimeric compounds are composed by mixtures of homodimers (C-12/C-12) and heterodimers (C-12/C-14). The interfacial properties of these non-ionic gemini surfactants are described.
