Viscoelastic Conjugated Polymer Fluids

Angewandte Chemie International Edition, 2019
AbstractThe introduction of optoelectronic functions into viscoelastic polymers can yield highly sophisticated soft materials for biomedical devices and autonomous robotics. However, viscoelasticity and excellent optoelectronic properties are difficult to achieve because the presence of a large number of π‐conjugated moieties drastically stiffens a ...

Excitons In Conjugated Polymers

2005
Abstract The study of excitons in conjugated polymers has often been inspired by the treatment of excitons in bulk three-dimensional semiconductors (as described in Knox (1963)). A particle-hole excitation from the valence band to the conduction band in a semiconductor leaves a positively charged hole in the valence band and a negatively

Conjugated polymers for enhanced bioimaging

Biochimica et Biophysica Acta (BBA) - General Subjects, 2011
Conjugated polymers (CPs) have been used for creating bioimaging tools or biosensors that provide a direct link between spectral signal and different biological processes. The detection schemes of these sensors are mainly employing the efficient light harvesting properties or the conformation sensitive optical properties of the CPs. Hence, the presence

Conjugated Polymers in an Arene Sandwich

Journal of the American Chemical Society, 2006
A series of poly(p-arylene butadiynylene)s containing zero, one, and two co-facial pi-pi interactions per repeat unit were synthesized and characterized. A surprisingly selective and high-yielding Diels-Alder cycloaddition of anthracene and nonsymmetric, sterically hindered anhydrides proved essential to generating the cofacial arene-containing ...

Amplitude breathers in conjugated polymers

Physical Review B, 1989
Nonlinear adiabatic dynamics of electron-phonon models of /ital trans/-(CH)/sub /ital x//, /ital cis/-(CH)/sub /ital x//, and (/ital AB/)/sub /ital x//-type polymers are studied. Using both analytic low-amplitude expansion and numerical simulations, we find the existence of charge-neutral breathers---spatially localized, time-periodic nonlinear ...

Conformational disorder of conjugated polymers

The Journal of Chemical Physics, 2006
Conformational disorder of conjugated polymers is an important issue to be understood and quantified. In this paper we present a new method to assess the chain conformation of conjugated polymers based on measurements of intrachain energy transfer. The chain conformation is modeled on the basis of monomer-monomer interactions, such as torsion, bending,
