摘要：

A new symmetric azobenzene compound (A) with triple alkoxy chain in each terminal was synthesized via Cu(I). catalyzed amino coupling reaction as the key step. The structure of this compound was identified with H-1 NMR, C-13 NMR and elemental analysis. The property of compound A was investigated by UV-Vis spectroscopy and scanning electron microscopy(SEM). The results showed that compound A can form organolgels with different organic solvents, and the sol. gel transition could be observed under UV and visible light irradiation. The SEM images of xerogels of compound A showed the formation of three-dimensional networks composed of entangled fibrous aggregates. The gels were heating., light- and mechan- responsive. The UV. Vis spectroscopy confirmed the photoresponsible behavior of compound A.
