Abstract:
An organic compound, a donor–acceptor conjugatedpolymer, a formulation and a thin film, wherein a solution of the donor–acceptor conjugated polymer exhibits a peak optical absorption spectrum red shift of at least 100 nm when the donor–acceptor conjugated polymer solution is cooled from 140℃ to room temperature.
Abstract:
Yellow electrochromic polymers (ECPs) are prepared that display a yellow neutral state and a highly transmissive oxidized state. The ECPs are copolymers where a dyad of dioxyhetereocyclic repeating units alternate with a monad of an aromatic repeating unit. An alternate yellow ECP has an oxidation potential of 450 mV or less and is an alternating copolymer of an acyclic dioxythiophene (AcDOT) or a propylene dioxythiophene (ProDOT) with an aromatic repeating unit that has an electron donating substituent. The yellow ECPs can be processed from solution for electrochromic devices.
Abstract:
The present invention relates to compounds comprising a tetra-aryl indacenodithiophene-based structural unit, the synthesis of such compounds as well as their use in organic electronic devices. The invention further relates to organic electronic devices comprising such compounds.
Abstract:
Donor-acceptor conjugated polymers, their precursors, synthesis and use. Electron-accepting (A) and electron-donating (D) repeat units having a conjugated polymer backbone are able to operate under both positive and negative bias, making a device with a relatively high operating voltage possible. The specific energy and specific power exceeds what is attainable with conventional conjugated polymers.
Abstract:
A formulation is provided which comprises an organic solvent, a fullerene, and a conjugated polymer. The solution of the conjugated polymer exhibits a peak optical absorption spectrum red shift of at least 100nm when the conjugated polymer solution is cooled from 120℃ to room temperature. The fullerene is not phenyl-C71-butyric-acid-methyl-ester. Further, the fullerene is not phenyl-C61-butyric-acid-methyl-ester.
