Title:
電荷輸送材料、それを用いた薄膜及び有機電子デバイス、並びにパイ電子系化合物
Document Type and Number:
Japanese Patent JP5574410
Kind Code:
B2
Abstract:
To provide a new charge transport material, and a thin film and an organic electronic device such as an organic electroluminescent element, an organic field effect transistor and an organic solar cell using the charge transport material, and to provide a new pi-electron-based compound useful as the charge transport material.
The new charge transport material including a pi-electron-based annular mother nucleus (for instance, an anthracene unit and a tetracene unit) being a pi-electron-based unit is provided, and the organic electronic device using these materials is provided. The charge transporting material contains at least one kind of the pi-electron-based compound represented by either of formulas (I) and (II). In formulas (I) and (II), Ar1and Ar2are each a five-membered or six-membered aromatic ring; R0s are each a hydrogen atom or a non-aromatic substituted group and may be identical to or different from one another; R1and R2are each a substituted or non-substituted aryl group or a heteroaryl group that may be condensed; L1and L2are each a single bond or a bivalent linking group; R3and R4are each a substituted group and may be bonded to each other to form a ring if possible; m1 and n1 are each an integer of 0 to 3 when Ar1and Ar2are each a five-membered ring, and an integer of 0 to 4 when Ar1and Ar2are each a six-membered ring; and m2 and n2 are each an integer of 0 to 4; and p is 0 or 1.
