✦ Synopsis
Perylene / Terrylene / buy-Substitution / Steric strain The synthesis of two novel n-alkyl-or aryl-substituted perylenes and of an n-alkylated terrylene is possible by an alkalimetal induced cyclization of the corresponding bi-or trinaphthyls. Differences in reactivity of the naphthylenes in the ring-closure reaction are caused by the different substitution pattern. UV and fluorescence spectra as well as the stability of the resulting rylenes[*] are discussed as a function of substitution.
