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.

A topologically new stilbene–anthracene dendrimer has been prepared using a highly branched tristilbenyl dendron derived from tetraphenylmethane. Steady-state photophysical studies on this dendrimer showed energy transfer from the peripheral stilbene units to the anthracene core.
