Dynamic combinatorial synthesis of donor-acceptor catenanes
… the discovery of a new generation of donor-acceptor [2]catenanes in aqueous dynamic combinatorial systems. The assembly of these [2]catenanes is promoted by a high salt concentration (1 M NaNO3), which raises the ionic strength and encourages hydrophobic association. More importantly, a …

Electrical characterization of large-area donor-acceptor molecular junctions
… properties of five different donor – bridge – acceptor large-area monolayer molecular junctions show current rectification. Langmuir-Blodgett deposition onto thermally evaporated gold yielded four out of the five monolayers. The fifth system was as a monolayer formed by self-assembly onto …

Donor-Acceptor Block Copolymers for Charge Separation at Nanostructured Interfaces
… a series of functionalized block copolymers, acceptor labeled polymers and low molecular weight model compounds were synthesized in which hole transport (donor), electron transport (acceptor) and light absorbing functionalities were incorporated. My approach was to use functionalized block …

Describing Charge Transfer in Extended Donor-Acceptor Systems with Density Functional Theory
… particular, the theoretical description of donor-acceptor (DA) systems is plagued by this shortcoming. DA systems are frequently used as light absorbing components in organic photovoltaic devices. The lowest electronic excitation in these molecules is usually influenced by CT. In order to support …
