Abstract:

Photoisomerization(trans-cis) of azoaromatic compounds has been investigated extensively using absorption spectroscopy since 1950s[1].By irradiation with light of wavelength λ1 or λ2,the geometric configuration of the azo bond in azobenzene based compounds can be reversibly switched from trails to cis.
