[摘要]:Organic Pigments, Fluorescent Brighteners, and Photographic A highly convergent [2+2+2] cyclotrimerization approach to anthracenes and 2-azaanthracenes has been developed. It allows for the facile introduction of the anthracene moiety on alkyne- and nitrile-bearing mols. and the rapid construction of compd. arrays. This is showcased in the assembly of a collection of fluorophores and their photochem. evaluation.
