Synthesis and photophysical properties of stilbenoid dendrimers via Heck reaction on a tetraphenylethylene core
Two new tetraphenylethylene-cored stilbenoid dendrimers have been efficiently prepared by fourfold Heck reaction with appropriate dendron molecules. The methodology permits highly trans-selective coupling. The optical absorption and emission properties of these systems were studied. The materials display strong emission in the blue region.

Synthesis of dendritic stilbenoid compounds: Heck reactions for the periphery and the core
A convergent synthetic strategy for stilbenoid dendrimers is described in which multifold Heck reactions have been used to construct both the peripheral and the core stilbene units. Solution optical properties of one of the dendrimers indicated some energy transfer having taken place from the periphery to the core.
