| Title | Polycyclic fused ring type pi-conjugated organic materials |
| Abstract |
The invention provides a polycyclic fused ring type pi-conjugate organic material having excellent light-emitting and charge-transporting properties, an intermediate thereof and a preparation method thereof. A synthesizing method of the organic material is as follows: a starting material is dimetalated with an organometallic base thus dimetalated is trapped with an organosilicon reagent, then an intermediate is obtained the intermediate is allowed to react with a metal reductant, which causes an intramolecular reductive cyclization reaction to proceed thus a dianion intermediate is produced the dianion intermediate is trapped with an electrophile, thus forming the polycyclic fused ring type pi-conjugate organic material. |
