Self-assembly of Amphiphilic Linear Diblock Rod-Coil Molecules by Hydrogen Bond and π-π Stacking Interactions

Aromatic amphiphilic molecules（1） consisting of three biphenyl groups linked together with ether bonds as a rigid rod segment and poly（ethylene oxide） with the number of repeating units of 17 as a coil segment were synthesized, and their self-assembly behavior in the bulk state and aqueous solution...

Description
Summary:Aromatic amphiphilic molecules（1） consisting of three biphenyl groups linked together with ether bonds as a rigid rod segment and poly（ethylene oxide） with the number of repeating units of 17 as a coil segment were synthesized, and their self-assembly behavior in the bulk state and aqueous solution was investigated. In bulk, molecules 1 self-assembled into 1-D lamellar structure in the solid state or smectic A phase in the liquid crystalline phase via the cooperative effects of ？-？ stacking, micro-phase separation and hydrogen bond interactions. In dilute aqueous solutions, molecules 1 were observed to selfassemble into cylindrical micelles owned uniform diameter and length of hundreds of nanometers.
