Conjugated polymers containing 2,3-dialkoxybenzene and iptycene building blocks.
[structure: see text]. New poly(phenylene ethynylene)s (PPEs) and poly(phenylene vinylene)s (PPVs) that are highly emissive in solution and thin films were prepared utilizing palladium-catalyzed cross-coupling between new 1,4-diiodo-2,3-dialkoxybenzene- and iptycene-containing monomers. The absorption and emission spectra of the resulting polymers consistently showed a significant blue shift re...
متن کاملElectron-hole versus exciton delocalization in conjugated polymers: the role of topology
There is currently a great need for solid state lasers that emit in the infrared. Whether or not conjugated polymers that emit in the IR can be synthesized is an interesting theoretical challenge. We show that the requirement for such a material is that the exciton delocalization in the system be large, such that the optical gap is small. We develop a theory of exciton delocalization in conjuga...
متن کاملBuilding Blocks for Electron Counting Arithmetic
The ability to control the transport of individual electrons in SET technology introduces a broad range of new possibilities and challenges for implementing computer arithmetic circuits. In this paper, we first briefly discuss the concept of electron counting based arithmetic. Second, we introduce the types of building blocks that are required in order to implement this concept in SET technolog...
متن کاملExtended conjugated microporous polymers for photocatalytic hydrogen evolution from water.
Conjugated microporous polymers (CMPs) have been used as photocatalysts for hydrogen production from water in the presence of a sacrificial electron donor. The relative importance of the linker geometry, the co-monomer linker length, and the degree of planarisation were studied with respect to the photocatalytic hydrogen evolution rate.
متن کاملEnd–Functionalized Polymers: Versatile Building Blocks for Soft Materials
We present a concise review of telechelic polymers of various architectures, focusing on the structure, solute solvent interactions, aggregation processes, equilibrium and dynamical properties and applications. Telechelics are macromolecules with functionalized, mutually attractive endgroups, which assume a variety of conformations that depend on solvent quality, salinity and pH of the solvent,...
