Title:
&pgr -CONJUGATED ORGANIC MATERIAL OF POLYCYCLIC FUSED RING TYPE, INTERMEDIATE THEREFOR, AND PROCESS FOR PRODUCING &pgr -CONJUGATED ORGANIC MATERIAL OF POLYCYCLIC FUSED RING TYPE
Document Type and Number:
WIPO Patent Application WO/2004/018488
Kind Code:
A1
Abstract:
A &pgr -conjugated organic material of the polycyclic fused ring type which is obtained by reacting a linear hydrocarbon comprising a triple bond and a hydrocarbon which is a benzene ring having an organosilicon as a substituent (an arylacetylene compound or phenylacetylene compound) with a metallic reducing agent to cause an intramolecular reductive cyclization reaction to proceed between the silicon and a carbon having the triple bond; and a process for producing the &pgr -conjugated organic material of the polycyclic fused ring type. The &pgr -conjugated organic material of the polycyclic fused ring type is applicable to luminescent materials, e.g., an organic electroluminescent (EL) element, and charge-transporting materials.
