Investigating the role of chain and linker length on the catalytic activity of an H2 production catalyst containing a β-hairpin peptide.

ABSTRACT: Building on our recent report of an active H2 production catalyst [Ni(PPh 2NProp-peptide)2]2+ (Prop = para-phenylpropionic acid, peptide (R10) = WIpPRWTGPR-NH2, p = D-proline and P2N = 1-aza-3,6-diphosphacycloheptane) that contains structured β-hairpin peptides, here we investigate how H2 production is effected by: (1) the length of the hairpin (eight or ten residues) and (2) limiting the flexibility between the peptide and the core complex by altering the length of the linker: para-phenylpropionic acid (three carbons) or para-benzoic acid (one carbon). Reduction of the peptide chain length from ten to eight residues increases or maintains the catalytic current for H
