9,10-bis{2-[4-(N,N-diphenylamino)phenyl]ethynyl}anthracene

The crystal structure of the title compound, C54H36N2, shows that the anthracene rings in the unit cell do not stack in a face-to-face manner. Instead, the anthracene rings are positioned over the planar N atom of the triphenylamino group.

A general method for the formation of aryl-sulfur bonds using copper(I) catalysts

[GRAPHICS] We report a mild, palladium-free synthetic protocol for the cross-coupling reaction of aryl iodides and thiols using 10 mol % Cul and 10 mol % neocuproine, with NaOt-Bu as the base, in toluene at 110 degreesC. Using this protocol, we have…

A general method for the formation of diaryl selenides using copper(I) catalysts

We report a mild, palladium-free synthetic protocol for the cross coupling reaction of aryl iodides and phenyl selenol using 10 mol% CuI/neocuproine, NaOt-Bu or K2CO3 as base, in toluene, at 110degreesC. Using this protocol, we show that a variety of…

A straightforward route to electron transporting conjugated polymers

We report a straightforward synthetic method to generate solution processable electron transporting polymers with low band gap and wide absorption range from readily available acceptor monomers. We show the efficacy of this approach using widely used…

AN ORGANIC-SOLID WITH WIDE CHANNELS BASED ON HYDROGEN-BONDING BETWEEN MACROCYCLES

Research on microporous solids has focused largely on inorganic materials such as aluminosilicates (zeolites), aluminophosphates, pillared clays and other layered materials(1,2). An elusive goal has been the design of new materials with specific…

Analysis of Charge Transport and Device Performance in Organic Photovoltaic Devices with Active Layers of Self-Assembled Nanospheres

Nanoparticle (NP) assemblies are particularly appealing as active layers of organic photovoltaic (OPV) devices because their aqueous synthesis reduces the usage of chlorinated solvents and because the nanoparticle size, ratio, and internal structure…

Analysis of hole transport in thin films and nanoparticle assemblies of poly(3-hexylthiophene)

We report numerical simulation results on hole transport in layers of the organic polymer poly(3-hexylthiophene) (P3HT) of different nanostructures based on a deterministic, phenomenological drift diffusion-reaction model that accounts for hole…
