| Abstract: | [structure: see text] A novel, rapid, inexpensive, and highly efficient convergent approach for the synthesis of a Fréchet- type aryl ether dendrimer using thionyl chloride has been developed. In this method, the purification of each dendron and a dendrimer occurs by recrystallization, extraction, and precipitation. The MALDI-TOF MS spectrum supported the formation of the G2, G3, and G4 dendrons and the star-shaped G4 dendrimer. |
