A series of 1,3,5-tricyano-2,4,6-tris(styryl)benzene derivatives and dendrimers have been synthesized. When the octupolar molecules are linked to the 1,3,5-position of the benzene ring by flexible ether linkages, the first hyperpolarizability (β(0)) value increases 1.7 fold. An octupolar monodendron (see Figure) exhibits β(0) = 507 × 10–30 esu, one of the largest β(0) values reported for octupolar molecules.
