摘要:
The invention concerns the use, as electroluminescent materials, of polymers containing structural units of general formula (I) -[A?1-(A2)C=CH-A3-CH=C(A2¿)]-, wherein A?1, A2 and A3¿, which are identical or different, designate mono and/or polynuclear aryl and/or heteroaryl groups which are optionally linked via one or a plurality of bridges, and preferably via one bridge, and/or are condensed and can be optionally substituted, and wherein A?1 and A3¿ each have two bonds and A2 has one bond. The polymers of formula (I) according to the invention are distinguished above all by their high degree of stability at high fluorescence quantum yields.

摘要:
Provided are a novel organic compound appropriate for emission of green light and an organic light-emitting device including the organic compound. Provided is a substituted or unsubstituted indeno[1,2,3-cd]naphtho[2,3-k]fluoranthene appropriate for emission of green light. The substituents of the indeno[1,2,3-cd]naphtho[2,3-k]fluoranthene are each independently selected from a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted amino group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heterocyclic group.
摘要:
A norbornene derivative characterized by being represented by the following general formula (Im). It is a novel norbornene derivative useful as a precursor monomer for producing a cycloolefin polymer which is excellent in transparency and heat resistance and reduced in water absorption and the birefringence and wavelength dispersion of which have been regulated at will. Also provided is a norbornene polymer produced by ring-opening (co)polymerization which is excellent in transparency and heat resistance, has high solubility in organic solvents, and has peculiar birefrengence and wavelength dependence.
