Conformational disorder of conjugated polymers: Implications for optical properties

The Optical Signature of Charges in Conjugated Polymers

Electrical charge flowing through organic semiconductors drives many of today's mobile phone displays and television screens, suggesting an internally consistent model of charge-carrier properties in these materials to have manifested. In conjugated polymers, charges give rise to additional absorption of light at wavelengths longer than those absorbed by the electrically neutral species. These ...

Extended 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.

Optical properties of nondegenerate ground-state polymers: Three dioxythiophene-based conjugated polymers

We report the optical properties of three dioxythiophene-based conjugated polymers: poly~3,4ethylenedioxythiophene! poly~3,4-propylenedioxythiophene!, and poly„3,4-~2,2-dimethylpropylenedioxy!thiophene.... Films of ca. 200 nm thickness of these polymers were prepared on indium-tin-oxide coated glass substrates using a potentiostatic electropolymerization method. The reflectance and transmittanc...
