Abstract

Enantiomerically pure, axially chiral (S)-1,1'-bi-2-naphthol was used as a core material to which Frechet-type dendritic wedges of the 0th up to the 4th generation were attached, yielding the axially chiral dendrimers. The chiroptical features of these compds. were studied and revealed an increasing molar optical activity for higher generations of dendrimers. This effect can be explained by a larger torsional angle between the naphthyl units, caused by steric repulsions between the dendritic wedges. However, the effect is marginal, indicating a high degree of flexibility present in the axially chiral dendrimers
