Elementary processes in layers of electron transporting Donor-acceptor copolymers : investigation of charge transport and application to organic solar cells
Donor-acceptor (D-A) copolymers have revolutionized the field of organic electronics over the last decade. Comprised of a electron rich and an electron deficient molecular unit, these copolymers facilitate the systematic modification of the material's optoelectronic properties. The ability to tune …

Synthesis of Highly Ordered Polymer Nanostructures Based on Polyphenylene Vinylenes (PPVs)
… broad, red-shifted emission for septamer PPV copolymers with tetraethylene glycol linkers, which suggests stronger inter-chromophore interactions in the solid state. Such low energy complexes were not observed in smaller PPV chromophore polymers. Single-molecule excitation polarization …

Acenaphthylene Based CP-PAH Materials for Organic Semiconductors
… large scale synthesis. The investigation of new donor-acceptor copolymers incorporating acenaphthylene or cyclopenta[cd]perylene units was also explored. Since the molecular scaffolds of the desired polymers have structural resemblance and electron affinities compared to bis-imide rylene dyes …

SYNTHESIS OF CONJUGATED SMALL MOLECULES AND POLYMERS BY A PALLADIUM CATALYZED CYCLOPENTANNULATION STRATEGY – TOWARDS NEW ORGANIC SEMICONDUCTORS
… still the predominant materials used as electron acceptors for OPV applications. By taking advantage of the electron accepting behavior of cyclopenta[hi]aceanthrylene fragment of C70, we have designed and synthesized new materials based on cyclopenta-fused polycyclic aromatic hydrocarbons …

Charge and Thermoelectric Transport in Semicrystalline Conjugated Polymers and Single-Walled Carbon Nanotube Networks
… two decades the development of high-mobility donor-acceptor copolymers outperforming amorphous silicon, employed in commercial display technologies, and the ability to tune the diameter distribution in SWCNT networks via selective dispersion with conjugated polymers and other sorting methods …
