Abstract
The synthesis of the 4,5-bis(3′,5′-di-tert-butylphenylethynyl)-2-methoxy-phenol from 3,5-ditertbutyl phenol,trifluoromethanesulfonic anhydride and 4,5-diethynyl-2-methoxyphenol was reported,by introduction of the 4,4'-bis(trimethylsilylethynyl)azobenzene to its hydroxyl,the first generation unsymmetrical conjugated phenylacetylene dendrimer with an azobenzene core(PAD-G1) was obtained.1H NMR characterization showed that the target product was synthesized successfully.The PAD-G1 had a strong absorption to the ultraviolet light range from 200 nm to 425 nm,and it can emit blue fluorescence under the ultraviolet light.
