Abstract: A polymer dye has repeating units of formula (I): Each of R1, R2, and R3 is independently a monocyclic carbocyclic group, a condensed polycyclic carbocyclic group, a monocyclic heterocyclic group, or a condensed polycyclic heterocyclic group. In any case, each of R1, R2, and R3 independently may have a substituent. R1 is a divalent group, and R2 and R3 are monovalent groups. D is an organic dye group and n is an integer of from 0 to 10. The polymer dye has a number-average molecular weight of from 500 to 500,000. The dye can be a component in a film. The dye can also be included in various industrial materials in automobiles; communication instruments, such as mobile phones, PDA, remote controllers, mobile information terminals, electronic dictionaries, and electronic organizers; home electric appliances; construction parts; and the like.

Abstract: The present invention provides novel polyaminopyridines which are excellent in solubility in various solvents, and are preferably used in a polymer-type organic electroluminescent material, and a process for preparing the same. More particularly, the present invention provides polyaminopyridines having a repetition structural unit represented by the following general formula (1); and having a number average molecular weight in a range of 500 to 1000000.

Abstract: An electroluminescent element includes an organic compound layer formed of a thiophene polymer as a light emitting layer or a hole injection transport layer. The element emits light at high luminance and is reliable.

Abstract: An isoquinoline polymer having a degree of polymerization of at least 5 is produced from an (iso)quinoline dihalide by a reaction with a zero-valent nickel compound, or an electrolytic reduction in the presence of a nickel compound. Since it is excellent in heat-resistivity and soluble in organic solvents, this polymer can be shaped by a dry-process into fibers, films or the like. Its depolarization degree and electrochemical oxidation-reduction potential can be controlled according to its structure.

Abstract: A quaternary (iso)quinolinediyl polymer having a degree of polymerization of at least 5 is produced from an (iso)quinoline polymer by reacting with an alkyl halide and quaternizing the nitrogen atom in ring. Since it is soluble in water and organic solvents, this polymer can be shaped by a dry-process into fibers, films or the like, and had clear change of its color by chemical and electrochemical oxidation reduction.
