Abstract: A novel azo compound with ‘dumbbell shape’ was synthesized successfully and characterized by MALDI-MS, FTIR, elemental analysis, 1H NMR and 13C NMR. UV-Vis spectrum was used to monitor the trans-cis isomerization and theoretical calculations were used to modelize the trans and cis isomers. The trans and cis isomers of the ‘dumbbell shape’ azo compound are both stable at room temperature because of the large end group.

Key words: Azobenzene, Dumbbell, UV-Vis spectrum, cis-trans isomerization, Theoretical calculation
