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
Martin L. Kirk,David A. Shultz,Daniel E. Stasiw,Geoffrey F. Lewis,Geoffrey F. Lewis,Guangbin Wang,Candice L. Brannen,Roger D. Sommer,Paul D. Boyle,Paul D. Boyle +9 more
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.

Electronic and Exchange Coupling in a Cross-Conjugated D–B–A Biradical: Mechanistic Implications for Quantum Interference Effects
Martin L. Kirk,David A. Shultz,Daniel E. Stasiw,Diana Habel-Rodriguez,Benjamin W. Stein,Paul D. Boyle +5 more
TL;DR: The results reveal important excited-state contributions to the ground-state singlet-triplet splitting in this cross-conjugated D-B-A biradical that contribute to the understanding of electronic coupling in cross- Conjugated molecules and specifically to quantum interference effects.

Chromophore-radical excited state antiferromagnetic exchange controls the sign of photoinduced ground state spin polarization
TL;DR: In this article, a change in the sign of the ground-state electron spin polarization (ESP) is reported in complexes where an organic radical (nitronylnitroxide, NN) is covalently attached to a donor acceptor chromophore via two different meta-phenylene bridges.
Determining the Conformational Landscape of σ and π Coupling Using para-Phenylene and “Aviram–Ratner” Bridges
Daniel E. Stasiw,Jinyuan Zhang,Guangbin Wang,Ranjana Dangi,Benjamin W. Stein,David A. Shultz,Martin L. Kirk,Lukasz Wojtas,Roger D. Sommer +8 more
TL;DR: The torsional dependence of donor-bridge-acceptor (D-B-A) electronic coupling matrix elements and the pairwise exchange interactions are further illuminated in three-dimensional, "Ramachandran-type" plots that relate D-B and B-A torsions to both electronic and exchange couplings.
Spectroscopic Signatures of Resonance Inhibition Reveal Differences in Donor-Bridge and Bridge-Acceptor Couplings
David A. Shultz,Martin L. Kirk,Jinyuan Zhang,Daniel E. Stasiw,Guangbin Wang,Jing Yang,Diana Habel-Rodriguez,Benjamin W. Stein,Roger D. Sommer +8 more
TL;DR: The work provides new detailed insight into the effects of torsional rotations which contribute to inhomogeneities in experimentally determined exchange couplings, electron transfer rates, and electron transport conductance measurements.
