A variety of thermally stable 4-(N,N-diarylamino)-4'-nitroazobenzene dyes can be produced by direct copper-mediated C-N bond formation on preformed amino substituted azo dyes, thus avoiding a troublesome azo coupling step; the products are useful chromophores for high temperature nonlinear optical applications.
