ABSTRACT:
The invention describes a helicene compound having the structure ##SPC1##
which contains seven six-membered conjugated aromatic rings capped by two five-membered rings which do not superimpose on each other.
The invention also describes a helical metallocene oligomer capped by unsaturated five-membered rings, having the structure: ##SPC2##
wherein M is a transition metal halide and n=1 to 100.
Method for the preparation of these compounds are also presented.
