    • A polycyclic fused ring type π-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 π-conjugated organic material is obtained. The polycyclic fused ring type π-conjugated organic material, an intermediate therefor, a method for producing the polycyclic fused ring type π-conjugated organic material, and a method for producing the intermediate make it possible to provide a polycyclic fused ring type π-conjugated organic material having excellent light-emitting and charge-transporting properties.
    • 以下列方式获得多环稠环型共轭有机材料(VIIa,VIIb,VIIc,VIId)。 也就是说,如下面的方案1所示,起始原料(I)用有机金属碱进行二价金属化。 用二氧化硅原料(I:(1)n-BuLi或t-BuLi;(2)HMe 2 SiCl)捕集由此得到的原料(I)。 结果得到中间体。 然后使中间体与金属还原剂反应。 这导致进行分子内还原环化反应。 结果,产生二价阴离子中间体。 将二价阴离子中间体用亲电子试剂(ii:(1)LiNaph,THF,rt,5分钟;(2)亲电子试剂或NH 4 Cl)捕获。以这种方式,获得多环稠环型共轭有机材料。 多环稠环型共轭有机材料,其中间体,多环稠环型共轭有机材料的制造方法以及中间体的制造方法可以提供多环稠环型&pgr 具有优异的发光和电荷传输性能的共轭有机材料。
