Substitution of an anthracene nucleus on an unsaturated linkage leads to a drastic change in the isomerization of the double bond: from the traditionally recognized mutual two-way isomerization between the cis and trans isomers to a unique one-way isomerization, solely from cis to trans isomers, through a quantum chain process. Many olefins have been shown to undergo one-way isomerization in an adiabatic way at the triplet state. This article describes the feature of the one-way adiabatic isomerization of aromatic olefins and imines and structural factors that control the mode of the isomerization. The nature of the quantum chain process in the triplet isomerization is described. Finally, another feature of anthracene-substituted unsaturated compounds, undergoing internal rotation in the excited state, is also described.
