Exciton delocalization drives rapid singlet fission in nanoparticles of acene derivatives.

Ryan D Pensack et al.

Journal of the American Chemical Society, 137(21), 6790-6803 (2015-05-07)

We compare the singlet fission dynamics of five pentacene derivatives precipitated to form nanoparticles. Two nanoparticle types were distinguished by differences in their solid-state order and kinetics of triplet formation. Nanoparticles that comprise primarily weakly coupled chromophores lack the bulk

Total, elastic, and inelastic cross sections for positron and electron collisions with tetrahydrofuran.

Luca Chiari et al.

The Journal of chemical physics, 138(7), 074301-074301 (2013-03-01)

We present total, elastic, and inelastic cross sections for positron and electron scattering from tetrahydrofuran (THF) in the energy range between 1 and 5000 eV. Total cross sections (TCS), positronium formation cross sections, the summed inelastic integral cross sections (ICS)
