A topologically new stilbene dendrimer is prepared using rigid caltrop-shaped dendrons derived from tetraphenylmethane. The dendrimer by virtue of its highly branched periphery, showed a strong emissive property with little excimer formation, even at the first generation.

The trigonally symmetric tris[4-(ferrocenylvinyl)-3-methylphenyl]methylium
ion 4, a π-conjugated metallocene
analog of Crystal Violet, has been prepared and shows strong absorption in
the near-infrared region (λmax = 1068 nm).
