The synthesis of 2,3,5,6‐tetrakis(2,6‐difluorophenyl)di(styryl)benzene by using a conventional synthetic sequence, including Diels–Alder and Horner reactions is reported. The target is an effective aggregation‐induced emitter. It is photostable with respect to electrocyclization, due to the presence of the fluorine substituents. This compound undergoes photochemical trans / cis isomerization of its styryl double bonds.
