Selenoviologens‐appendant metallacycles M1 (rhomboid) and M2 (hexagonal) were synthesized and utilized in electrochromism and photocatalysis, as reported in the Research Article (e202209054) by Gang He et?al. The highly stable radical cations and long‐lived charge separation states of the selenoviologens (SeV2+) originate from the metallacyclic effect. Their properties were validated by femtosecond transient absorption (fs‐TA), demonstrating the vital role of the metallacycle in organic photocatalytic reactions.
