We investigated the polymorph structures of benzyl (Z,Z)-muconate crystals (ZZ-Bn-α, β, and γ) and their EZ photoisomerization behavior in order to clarify the EZ isomerization mechanism of diene compounds in the solid state. First, the thermodynamics and crystal phase transition of the polymorphs w...
