The dynamic properties of photoinduced alignment and surface relief grating (SRG) formation asafunction ofexcitationwavelength(lex ¼454,488,514,532,568,and 647nm)areexamined using five azobenzene-derivative polymers, whose absorption spectra are tuned by substituting different electron-withdrawing groups (CF3, CN, CNCl, NO2, (CN)2). The dynamics sensitively depend on lex. The fastest rate of photoinduced alignment is observed when lex is between lmax of
