摘　　要：As an important functional group,azo derivatives(-N=N-)have attracted wide attention due to their excellent properties,for their narrow bandgap,Lewis base property,photo-isomerization and redox activity,in chemistry and materials science fields[1].Among them,azo-benzene is one of the most popular candidates of optical molecular devices including easy synthesis,high quantum yields and fast switching.Generally,azo-benzene exists in two conformations,i.e.trans-state and cis-state,which are reversibly conversed via-N=N-bond transformation in the presence of appropriate stimuli including temperature,mechanical stress,electric field,and especially photoirradiation[2].In addition,the azo group can not only endow the derivatives with narrow bandgap properties.
