発明の名称 (英語) Condensed polycyclic π-conjugated organic material, intermediate product therefor, and method of manufacturing condensed polycyclic π-conjugated organic material
発明の概要(英語) (US7705174)
The invention provides condensed polycyclic &pgr;-conjugated organic materials and manufacturing methods for the materials.
A metal reducing agent is reacted with a straight-chain, triple bond-containing hydrocarbon (aryl acetylene compound, phenyl acetylene compound), the hydrocarbon being a benzene ring with an organic silicon as a substituent, so as to allow an intramolecular reductive cyclization reaction to proceed between the silicon and the triple-bond carbon.
The reaction produces condensed polycyclic &pgr;-conjugated organic materials of the invention.
The invention provides light-emitting materials applicable for organic electroluminescent devices, condensed polycyclic &pgr;-conjugated organic materials applicable for charge transport materials, their intermediate products, and a manufacture method for condensed polycyclic &pgr;-conjugated organic materials.
