An organic EL device employing polymer material includes a structure in which a luminous layer formed of a polymer indicated byis put between a lower electrode and an upper electrode. Where, in the above chemical formula, Ar, Ardenote a allylene group respectively, R, R, R, Rdenote a substituent respectively, and n denotes a copolymerization ratio. Accordingly, the flatness of the luminous layer can be improved and the solubility of the luminous layer constituent material can be enhanced.

This invention relates to a process for producing an organic semiconductor. More specifically, it relates to a process for producing an electrically conductive acetylene high polymer, which comprises doping an acetylene high polymer having a fibrous microcrystalline (fibril) structure with a specified electron acceptor compound, having low toxicity, to obtain an electrically conductive acetylene high polymer having an increased electrical conductivity, and flexibility and heat stability.

Process for producing easily moldable composition of an acetylene high polymer by polymerizing acetylene using a catalyst system composed of (A) a transition metal compound containing at least one transition metal from Groups IVa, Va, VIa and VIII and (B) an organometallic compound containing at least one metal from Groups IIa, IIb, IIIb and IVb, the polymerization being carried out in a polymerization solvent containing the transition metal compound in a concentration of 0.0001 to 0.1 mole/liter to form a gel-like material consisting of an acetylene high polymer having a fibrous microcrystalline structure and the polymerization solvent.

Process for producing a porous acetylene high polymer by lyophilizing a gel-like composition composed of 1 part by weight of an acetylene high polymer having a fibril structure and 1 to 1,000 parts by weight of an organic solvent.

Electrically conducting organic polymeric material having a preselected room temperature p-type electrical conductivity which may vary over the entire range characteristic of semiconductor behavior and into the range characteristic of metallic behavior, is prepared by controlled chemical doping of polyacetylene in the form of a polycrystalline film. Exceptionally high room temperature p-type electrical conductivity within the range of from about 0.1 to of the order of 10.sup.3 ohm.sup.-1 cm.sup.-1 is achieved with several electron acceptor dopants, including bromine, iodine, iodine chloride, iodine bromide and arsenic pentafluoride.
