Title Polycyclic fused ring type π-conjugated organic material, intermediate therefor, process for producing polycyclic fused ring type π-conjugated organic material, and process for producing intermediate of polycyclic fused ring type π-conjugated organic material
Abstract (US7973190)
A polycyclic fused ring type &pgr;-conjugated organic material (VIIa, VIIb, VIIc, VIId) is obtained in the following manner.
That is, as shown in Scheme 1 below, 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) HMe2SiCl).
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 NH4Cl) In this way, the polycyclic fused ring type &pgr;-conjugated organic material is obtained.
The polycyclic fused ring type &pgr;-conjugated organic material, an intermediate therefor, a method for producing the polycyclic fused ring type &pgr;-conjugated organic material, and a method for producing the intermediate make it possible to provide a polycyclic fused ring type &pgr;-conjugated organic material having excellent light-emitting and charge-transporting properties.
