Abstract

The divergent synthesis of star-shaped oligophenylene dendrimers is described. These latter consist of a triptycene central core decorated with various peripheral tetra- and octa-arylamine derivatives. The target compounds were prepared via a convenient [4 + 2] Diels–Alder cycloaddition reaction followed by palladium-catalyzed Buchwald–Hartwig Cross-Coupling reactions in very good overall yields. The dendritic structures were confirmed by ¹H- and ¹³C-nuclear magnetic resonance, high resolution mass spectrometry, and thermogravimetric analysis. Photophysical studies of these star-shaped dendrimers revealed their violet and blue fluorescent properties, thus, promoting them as promising materials for emission applications.
