Three metal covalent organic frameworks (MCOFs), namely RuCOF-ETTA, RuCOF-TPB and RuCOF-ETTBA, were synthesized by incorporating the photosensitive RuII tris(2,2'-bipyridine) unit into skeleton. Interestingly, each RuCOF contains three isostructural that interlock together with centers serving as point of registry. The covalently linked network coupling uniformly distributed units allowed RuCOFs to exhibit superior chemical stability, strong light-harvesting ability, high photocatalytic activity toward hydrogen evolution (20 308 μmol g-1 h-1 ). This work illustrates potential developing versatile MCOFs-based photocatalysts from functionalized complex building further enriches MCOFs family.
