Fluorenes and polyfluorenes having one or two polar-group-containing alkyl substituents on their '9' carbon methylenes are disclosed together with the polymers' use as luminescent materials in organic light-emitting diodes and light-emitting electrochemical cells.

Polyfluorenes as materials for photoluminescence and electroluminescence

An ohmic hole injecting electrode or contact for diode structures is disclosed. It is formed of multilayer composite materials and gives superior results in this application. The composite materials include a layer of a high work function inorganic material and a layer of conductive polyaniline ('PANI'). In preferred embodiments, the anode has substantial transparency. These preferred materials can function as transparent electrodes in light-related diodes such as LEDs and photovoltaic cells where they exhibit lower turn on voltages and higher efficiencies.

Bilayer composite electrodes for diodes

Polymer grids comprising a body of electrically conducting organic polymer, which body has an open and porous network morphology and defines an expanded surface area void-defining porous network are disclosed. In most applications active electronic material is located within at least a portion of the void spaces defined by the porous network. These grids are advantageously incorporated into polymer grid triodes and especially light-emitting polymer grid triodes.

Polymer grid triodes

A conductive layered product is made by adhering an oligothiophene compound to the surface of a polytetrafluoroethylene (PTFE), wherein the surface of said PTFE is oriented by an orientation treatment, and wherein the molecular chains of said oligothiophene compound are oriented and crystallized in the orientation direction of the PTFE, thus improving the orientation of the oligothiophene compound of a low molecular conductive material by a simple method. The oligothophene compound adhered to the PTFE oriented film is oriented and crystallized. A gaseous-phase method and a casting method are acceptable methods for adhering the compound. It is preferable to use oligothiophene compounds with 4-6 polymerization degrees. The oligothiophene compound, in which the .alpha. position at the end of molecular chains is replaced with an alkyl group, can also be used.
