摘要:
The objective of the present invention is to provide a blue light-emitting polymer capable of emitting blue light for a long time, and further excellent in durability, processes of producing the polymer, and a luminescent element. The blue light-emitting polymer of the invention has a repeating unit represented by formula (1):
wherein each of Ar 1 and Ar 2 is a benzene derivative, a naphthalene derivative, or an anthracene derivative. The present invention also provides processes of producing the blue light-emitting polymer, and a luminescent element including the polymer.

The invention relates to methods for the treatment of polyazole films, whereby a film is run at least twice through a vat filled with a liquid. The film is wound off one drum and onto another drum and the direction of the film is alternated during the treatment by changing the direction of rotation of the drums.

Block copolyoxadiazoles having formula (I), wherein R is an aliphatic residue, A is an aromatic residue, x is such that the inherent viscosity in decilitres per gramme is greater than 0,6, and n and n' are at least 2, and having two glass transition temperatures.
摘要:
Tractable doped electroactive polymers comprise a charged polymer backbone of recurring units of a 3,3'-N,N'-disubstituted-6,6'-bicarbazole-1,3,4-oxadiazole-2,5-diyl ring system, and a sufficient concentration of a charge-compensating ionic dopant associated therewith, the polymer backbone being capable of undergoing reversible oxidation to form the charged polymer backbone.
摘要:
Described are sulfonated naphthalene polyoxadiazole polymers with a high degree of sulfonation and good flammability properties. The polymer has repeat units of Formula (I) and one or both of Formula (II) and (IIa); wherein Q is SO3M and M is a cation. The polymers are useful in articles such as fibers.
