Excimers in light-emitting conjugated polymers

The electronic structures of the low-lying excited states for two parallel chains of poly (p-phenylene-vinylene! with arbitrary relative positions are studied. The interchain interaction is treated microscopically. The energy and charge transfer fraction of the ~light-emitting! lowest singlet state are found to depend sensitively on the horizontal shift of the two chains, which is in turn deter...

Light-Emitting Devices with Conjugated Polymers

This article introduces a previous study and tremendous progress in basic theoretical modeling, material developments and device engineering for polymer light-emitting devices (PLEDs).

Thia- and selena-diazole containing polymers for near-infrared light-emitting diodes

We report the optical characterization of near-infrared (NIR) emitters for polymer light-emitting diode (PLEDs) applications based on the copolymerization of a phthalimide-thiophene host polymer with a low-gap emitter containing the bisthienyl(benzotriazolothiadiazole) unit. We investigate different loadings of the low-gap emitter (in the range 1–3% by weight) and the substitution of a sulphur ...

Metal-containing and metallo-supramolecular polymers and materials.

Flexible and metal-free light-emitting electrochemical cells based on graphene and PEDOT-PSS as the electrode materials.

We report flexible and metal-free light-emitting electrochemical cells (LECs) using exclusively solution-processed organic materials and illustrate interesting design opportunities offered by such conformable devices with transparent electrodes. Flexible LEC devices based on chemically derived graphene (CDG) as the cathode and poly(3,4-ethylenedioxythiophene) mixed with poly(styrenesulfonate) a...
