Title Chalcogen-containing fused polycyclic organic material and method for producing same
Abstract (US8044218)
A diacetylene derivative was used as a starting material, and was subjected to dilithiation using an organolithium reagent.
The resulting product was allowed to react with an excessive amount of chalcogen.
Accordingly, an intramolecular cyclization reaction proceeded simultaneously with formation of skeletons of three rings.
As a result, a chalcogen-containing fused polycyclic organic material was found to be obtained which has the three rings and a dichalcogenid bond.
Further, by subjecting the resulting compound to a dechalcogenation reaction, a heteroacene was found to be obtained in a satisfactory yield.
These synthetic techniques have made it possible to synthesize a series of highly planar chalcogen-containing &pgr;-electron system materials.
Therefore, it is possible to provide (i) a chalcogen-containing fused polycyclic organic material capable of exhibiting excellent charge-transporting properties and (ii) a method for producing the material.
Scope of claims [claim1]
1. A chalcogen-containing fused polycyclic having a structure represented by following formula (11):
where E1 is S or Se, R2, R3, R6, and R7 are independently an aryl group, a hydrogen atom, an alkyl group, an alkoxy group, an alkylthio group, an aryloxy group, a silyl group, and R1, R4 5, and R8 are hydrogen atoms, wherein when E1 is S, R1, R2, R3, R4 R5, R6, R7, and R8 are not all hydrogen atoms wherein all said groups are unsubstituted.
[claim2]
2. A chalcogen-containing fused polycyclic organic material having a structure represented by following formula (12):
where E1 is S or Se, and R2, R3, R6, and R7 are independently an aryl group, a hydrogen atom, an alkyl group, an alkoxy group, an alkylthio group, an aryloxy group, a silyl group, and R1, R4, R5, and R8 are hydrogen atoms wherein all said groups are unsubstituted.
