Abstract
Symmetric dithienylethenes 9-12 bearing a variety of substituents were synthesized by a click chemistry approach. The starting material, diacetylene 4, was obtained through Wittig reaction of dialdehyde 1 with dibromomethyltriphenylphosphonium bromide (2) and subsequent treatment with a lithium base (Corey-Fuchs reaction). Triazoles 11 and 12 with covalently linked fluorophore moieties show reversible quenching of fluorescence in solution.
