OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.

Fluorene , or '9H-fluorene' is an organic compound with the formula (C6H4)2CH2. It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. Despite its name, it does not contain the element fluorine, but rather it comes from the violet fluorescence it exhibits. For commercial purposes it is obtained from coal tar, where it was discovered and named by Marcellin Berthelot in 1867.

1,3,5,7-Cyclooctatetraene (COT) is an unsaturated derivative of cyclooctane. It is a colorless flammable liquid at room temperature. COT is an antiaromatic compound as it possesses 8 π electrons. In contrast to the aromaticity commonly seen in benzene rings; antiaromaticity destabilises the COT molecule. This destabilisation effect is so strong that COT avoids it by adopting a non-planar 'tub' conformation, which prevents all of the π orbitals from forming a single conjugated system. As a result, COT possesses significant polyene character and will undergo many reactions that benzene rings wil

polymeric chemical substance which intrinsically conducts electricity

Polyacetylene (IUPAC name: polyethyne) usually refers to an organic polymer with the repeating unit . The name refers to its conceptual construction from polymerization of acetylene to give a chain with repeating olefin groups (a conjugated polyene). This compound is conceptually important, as the discovery of polyacetylene and its high conductivity upon doping helped to launch the field of organic conductive polymers. The high electrical conductivity discovered by Hideki Shirakawa, Alan Heeger, and Alan MacDiarmid for this polymer led to intense interest in the use of organic compounds in mic

Tetrathiafulvalene (TTF) is an organosulfur compound with the formula . It is the parent of many tetrathiafulvenes. Studies on these heterocyclic compound contributed to the development of molecular electronics, although no practical applications of TTF emerged. Over 10,000 scientific publications discuss TTF and its derivatives.

Naphthalocyanine is a cross-shaped organic molecule consisting of 48 carbon, 8 nitrogen and 26 hydrogen atoms. It is a derivative of phthalocyanine, differing by having 4 extra carbon rings, one on each "arm." IBM Research labs used it for developing single-molecule logic switches and visualizing charge distribution in a single molecule.
