The present specification relates to a polymer and an organic light emitting device using the same, wherein the polymer is represented by the following Chemical Formula 1:

E1-[A].sub.a—[B].sub.b—[C].sub.c-E2  [Chemical Formula 1] Wherein A, B, C, E1, E2, a, b and c are described herein.

Embodiments of the presently disclosed technology provide a synergistic combination of a conjugated open-shell donor-acceptor polymer with a carbon-based compound (e.g., reduced graphene oxide) to produce a composite electrode material which demonstrates state-of-the-art capacitance and potential window, with excellent kinetics and cycle life. The conjugated open-shell donor-acceptor polymer may comprise a plurality of alternating electron-rich monomers (i.e., donors) and electron-deficient monomers (i.e., acceptors) bonded together via a conjugated backbone. The conjugated backbone may comprise a connection of n-orbitals of the plurality of monomers in alternating single and double bonds that facilitates unpaired electron delocalization—thereby stabilizing charge for the polymer. The carbon-based compound of the composite electrode material may provide porous, conductive scaffolds for the composite electrode material, resulting in electrodes scalable to microns-thick films with fast kinetics.

An interpenetrating network (IPN) polymer membrane material includes a soft polyurethane interspersed with a crosslinked conducting polymer. The material can be reversibly “switched” between its oxidized and reduced states by the application of a small voltage, ˜1 to 4 volts, thus modulating its diffusivity.

The invention provides for UV excitable polyfluorene based conjugates and their use in methods of analyte detection.

The invention provides for new polymer compounds and methods for the preparation of modular narrow band gap conjugated compounds and polymers that incorporate exocyclic cross-conjugated donors or substituents, as well as novel monomer components of such polymers and the resulting products which comprise materials and useful electronic devices with novel functionality.

As a means for providing an electroluminescent device capable of achieving high luminance, high efficiency, and at the same time excellent device life-span, a polymer having an overlap index of greater than or equal to about 0.00001 and less than or equal to about 1.8, and a polymer including a structural unit represented by Chemical Formula (1) are provided:

An organic semiconducting compound and an organic photoelectric component containing the same are provided. The organic semiconducting compound has a novel chemical structure to make the organic semiconducting compound have good response to the infrared light. The organic semiconducting compound can be applied to the organic photoelectric components such as organic photodetector (OPD), organic photovoltaic (OPV) cell, and organic field-effect transistor (OFET). Thus, the organic photoelectric components have better light absorption range and photoelectric response while in use.
