The alkyne-functionalized Fréchet-type dendrons 2-Dm containing benzamine were synthesized by N-alkylation of the corresponding dendritic benzyl chlorides with 4-ethynylaniline. The oxidative homo-coupling reaction of the alkyne-functionalized Fréchet-type dendrons 2-Dm was allowed to provide the first through fourth generation dendrimers 3-Gm with 1,4-diphenylbuta-1,3-diynes at chromophore core in high yields. Their structure of dendrimers was confirmed by ¹H and ¹³C NMR spectroscopy, IR spectroscopy, mass spectrometry, and GPC analysis. The photophysical properties of the synthesized dendrimers was investigated.
