In the keV-energy regime, the scattering of krypton ions off a copper sample has been studied. In addition to the broad energy spectrum arising from multiple-collision scattering, the energy distributions of the backscattered ions exhibit prominent p

Three different benzodithiophene derivatives were designed to isolate the effects of bond topology from that of functional groups in quantum interference to examine the role of the quinone functionality separate from cross-conjugation.
Quantum i

We have employed x-ray and ultraviolet photoemission spectroscopies (XPS and UPS) to study the energy level alignment and electronic structure at the Co/pentacene/Co interfaces. In the case of pentacene deposition on Co we found an interfacial dipole

Molecules with Linearπ-Conjugated Pathways between All Substituents: Omniconjugation

Autor: Jan C. Hummelen, Harry T. Jonkman, M. H. van der Veen, Minze T. Rispens

Publikováno v: Advanced Functional Materials, 14(3), 215-223. WILEY-V C H VERLAG GMBH

In this paper, omniconjugation is introduced as a topological phenomenon in π-conjugated systems. Omniconjugated molecules are defined by the fact that they provide direct and fully π-conjugated pathways between all substituents attached to them. S

In this paper, time-dependent density functional theory (TDDFT) calculations of excited state polarizabilities of conjugated molecules are presented. The increase in polarizability upon excitation was obtained by evaluating the dependence of the exci
