The synthesis and characterization of four dendron-containing tetraphenylethylenes (TPEs), 1114, were synthesized, along with a TPE compound that contained four OCH2Ph groups (referred to as 10) for comparison. Photophysical studies revealed that the TPE core became emissive after linking dendrons onto its periphery. Moreover, the fluorescence intensity was significantly enhanced when high-generation dendrons were linked onto the TPE core; the fluorescence intensity increased in the following order: 11
