Synthesis and reactivity of nitridorhenium complexes incorporating the mercaptoethylsulfide (SSS) ligand

Dalton Transactions, 49, 6127–6134.

Solvate Structures and Spectroscopic Characterization of LiTFSI Electrolytes

JOURNAL OF PHYSICAL CHEMISTRY B, 118(47), 13601–13608.

By: D. Seo n, P. Boyle n, R. Sommer n, J. Daubert n, O. Borodin* & W. Henderson n

TL;DR: It is found, however, that significant difficulties may be encountered when identifying the distributions of specific forms of TFSI(-) anion coordination present in liquid electrolyte mixtures due to the wide range of T FS(-)···Li(+) cation interactions possible and the overlap of the corresponding spectroscopic data signatures.

Superexchange Contributions to Distance Dependence of Electron Transfer/Transport: Exchange and Electronic Coupling in Oligo(para-Phenylene)- and Oligo(2,5-Thiophene)-Bridged Donor–Bridge–Acceptor Biradical Complexes

Journal of the American Chemical Society, 135(45), 17144–17154.

By: M. Kirk*, D. Shultz n, D. Stasiw n, G. Lewis n, G. Wang n, C. Brannen n, R. Sommer n, P. Boyle n

TL;DR: The work provides a direct measurement of superexchange contributions to β, with no contribution from incoherent hopping, and offers unique insight into the intrinsic molecular factors that govern H(DA) and β, which are important for understanding the electronic origin of electron transfer and electron transport mediated by molecular bridges.

Synthesis, characterization and structural investigation of novel meso-pyridyl BODIPY–cobaloxime complexes

Dalton Transactions, 42(41), 14883.

By: J. Bartelmess n, W. Weare n & R. Sommer n

TL;DR: It is found that the synthesis of four boron-dipyrromethene (BODIPY) sensitized cobaloxime complexes as structural models of light-driven proton reduction catalysts produce sub-stoichiometric quantities of hydrogen under standard photon-driven hydrogen evolving conditions.
