Two novel perfluorodiarylethenes which contains a 2-methylbenzo[b]furane and a modified pyridine moiety were synthesized. Such structure may induce F⋯N or S⋯N heteroatom contact which was newly observed. Experiments results showed that the photocyclization quantum yield exhibited a strong correlation with the two weak intramolecular interactions, which behaved solvent independency. Moreover, both novel
