Homoconjugated push-pull chromophores are obtained by [2+2] cycloaddition of 2,3- dichloro-5,6-dicyano-p-benzoquinone to anilino or ferrocene donor-substituted alkynes, and in one case a spiro compound (see picture: examples with corresponding electron adsorption spectra; C gray, Cl green, N blue, O red). Significant third-order optical nonlinearities could be measured for the first time for homoconjugated push-pull systems.
