    Azo compounds are compounds which have—N = N—health, and azo group is a kind of optically active group, under the effect of light and heat,the Azo compound can be a cis-trans (trans - cis) and cis - trans (cis - trans) isomerization transition, when use the different wavelengths(入2 and入1 ) light the Azo compound,it can change between cis and trans, leading to its absorption characteristics are reversible changes. In recent years,Azobenzene and many of its derivatives are characterized by reversible transformations from the generally more stable trans form to the less stable cis form upon irradiation with UV or visible light to yield a photostationary composition that is wavelength and temperature dependent.

    所谓偶氮化合物,是指含有_N=N_健的化合物,偶氮基团是一种具有光学活性的基团,在热和光的作用下可以进行反顺式(trans-cis)或者顺式一反(cis-trans)可逆反应,用不同波长入1和入2(入1>入2)的光束对偶氮化合物进行照射,可以使其地在顺式一反之间进行可逆的转变,从而导致其吸收特性发生变化。
