pi-CONJUGATED ORGANIC MATERIAL OF POLYCYCLIC FUSED RING TYPE, INTERMEDIATE THEREFOR, AND PROCESS FOR PRODUCING pi-CONJUGATED ORGANIC MATERIAL OF POLYCYCLIC FUSED RING TYPE

摘要

A pi-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 pi-conjugated organic material of the polycyclic fused ring type. The pi-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.
