Abstract
A series of structurally related, acyclic cobalt tetrapyridyl hydrogen evolving catalysts (HEC) were prepared and characterized. The common motif, di(2,2′-bipyridin-6-yl)-methane, was derivatized at the bridging methylene to include a carbonyl group (L1), a hydroxy (L2), a methyl and a hydroxy (L3), a 1,1′-biphenyl-2,2′-diyl (L4), a hydroxy and a phenyl (L5) or a hydroxy and a pyrid-6-yl group. These catalysts were compared with the known HEC [Co(appy)Br]Br. Photo- and electrochemistry showed a distinct influence of the bridging posit
