Extended π-Conjugated Dendrimers based on Truxene.

Presents information on extended &b.pi;-conjugated dendrimers based on truxene. Preparation of a novel dendrimer containing up to nine truxene moieties with good yields; Difficulties in cyclotrimerizations due to steric hindrance of the giant truxene moiety; Affect of large torsion angle between the giant truxene moiety and the benzene ring on the full &b.pi;-delocalization of the whole molecule; Platform to synthesize a family of dendrimers utilizing giant polycyclic aromatics.
