Synthesis of a chiral micelle-like dendrimer with phenylene dendrons and a 1,1′-binaphthyl core

Abstract

A novel chiral micelle-like dendrimer has been synthesized. This dendrimer contains a chiral binaphthyl core, meta-phenylene dendrons, and hydrophilic polyhydroxyl periphery groups. It is soluble in highly polar solvents such H 2O/THF, MeOH/THF, EtOH/THF and DMSO, but insoluble in EtOAc, CH 2Cl 2 and CHCl 3. The study by UV–vis absorption spectroscopy reveals that the dendrimer may have a tighter conformation in a less polar solvent than in a more polar solvent. This dendrimer shows strong fluorescence in solution.
