The photocyclization of diarylethenes toward polycyclic aromatic hydrocarbons and analogs has been well-documented. However, stiff-stilbene was reported to be inactive, and examples of photocyclization-induced deamination remain unknown. Here, we report that ortho-(N,N-dimethylamino)-stiff-stilbene (1a) undergoes efficient photocyclization-induced deamination, forming the dicyclopenta-fused phenanthrene
