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

A novel chiral micelle-like dendrimer has been synthesized. This dendrimer contains a chiral binaphthyl core, meia-phenylene dendrons, and hydrophilic polyhydroxyl periphery groups. It is soluble in highly polar solvents such H2O;THF, MeOH THF, EtOH THF and DMSO. but insoluble in EtOAc, CH2Cl2 and CHCl3. 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. (C) 2001 Published by Elsevier Science Ltd.
