Abstract:
1. Asymmetric narcissistic molecules comprising polyene-linked bis-anthracenyl compounds that are optically active, have two terminal positions, and bear a dichalcogenide carbamate ester on one terminal position and a dichalcogenide iminium salt on the other terminal position, capable of undergoing valence tautomerization between degenerate cationic forms that are enantiomeric to each other, wherein the asymmetric narcissistic molecules comprise conjugated bis-anthracenyl derivatives having the structure: wherein: A X is independently selected from the group consisting of sulfur, selenium, and oxygen; the R and R n is 1; D is hydrogen or an auxochrome substituted on the molecular chromophore; W Z is a six-membered chiral ring system of atoms that changes chirality on tautomerization.
