発明の名称 (英語) POLYCYCLIC FUSED RING TYPE .PI.-CONJUGATED ORGANIC MATERIALS, INTERMEDIATE THEREFOR, PROCESS FOR PRODUCING POLYCYCLIC FUSED RING TYPE .PI.-CONJUGATED ORGANIC MATERIALS, AND PROCESS FOR PRODUCING INTERMEDIATE FOR POLYCYCLIC FUSED RING TYPE .PI.-CONJUGATED ORGANIC MATERIALS
発明の概要(英語)

A polycyclic fused ring type n-conjugated organic material (VIIa, VIIb, VIIc, VIId) is obtained in the following manner. A starting material (I) is dimetalated with an organometallic base. The starting material (I) thus dimetalated is trapped with an organosilicon reagent (i: (1) n-BuLi or t-BuLi

(2) HMe2SiC1). As a result, an intermediate is obtained. Thereafter, the intermediate is allowed to react with a metal reductant. This causes an intramolecular reductive cyclization reaction to proceed. As a result, a dianion intermediate is produced. The dianion intermediate is trapped with an electrophile (ii: (1) LiNaph, THF, rt, 5 min

(2) electrophile or NH4C1). In this way, the polycyclic fused ring type ri-conjugated organic material is obtained.

The polycyclic fused ring type n-conjugated organic material, an intermediate therefor, a method for producing the polycyclic fused ring type n-conjugated organic material, and a method for producing the intermediate make it possible to provide a polycyclic fused ring type n-conjugated organic material having excellent light-emitting and charge-transporting properties.
