the synthesis of a novel selenoviologen-based tetracationic cyclophane incorporating bipyridine pt(ii) is reported by gang he et al. in their research article (e202410525). this compound not only forms host–guest complexes with ferrocene but also facilitates directional electron flow from the selenoviologen units to the pt center. the efficient electron transfer under visible-light irradiation significantly enhances hydrogen production, offering a promising new strategy for improving photocatalytic performance.
