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.
