摘要:
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.

摘要:
The invention provides condensed polycyclic π-conjugated organic materials and manufacturing methods for the materials. A metal reducing agent is reacted with a straight-chain, triple bond-containing hydrocarbon (aryl acetylene compound, phenyl acetylene compound), the hydrocarbon being a benzene ring with an organic silicon as a substituent, so as to allow an intramolecular reductive cyclization reaction to proceed between the silicon and the triple-bond carbon. The reaction produces condensed polycyclic π-conjugated organic materials of the invention. The invention provides light-emitting materials applicable for organic electroluminescent devices, condensed polycyclic π-conjugated organic materials applicable for charge transport materials, their intermediate products, and a manufacture method for condensed polycyclic π-conjugated organic materials.
