✦ Synopsis

Enantiomerically pure, axially chiral (S)-1,1Ј-bi-2-naphthol has been used as a core material to which Fre ´chet-type dendritic wedges of the zeroth up to the fourth generation were attached, yielding the first axially chiral dendrimers 1؊5. The chiroptical features of these compounds were studied and revealed an increasing molar optical activity for higher
