The preparations and structures of three vaulted cyclidene complexes are compared with the two previously reported. All show similar structures with large rigid cavities partly closed off by the piperidine risers, illustrating in particular the attractive effect of van der Waals forces resulting in the incorporation of solvent molecules or [PF 6 ] - ions nesting on the edges of the...
We have prepared a histidine containing monomeric α-helical peptide, ETH6 (A 2 KA 4 KA 2 HA 6 HA 4 KA 4 K) in order to study long-range electron transfer (ET). This peptide was site-specifically labeled with a ruthenium (donor) at one histidine and a second ruthenium (acceptor) at a second histidine located on the same peptide. Both the unlabeled peptide...
