Organic semiconductor layer, electronic device, and method for manufacturing electronic device

An organic semiconductor layer comprising:

• a mixture of a first polycyclic aromatic hydrocarbon to which a first substituent R1 other than a hydrogen atom is bonded by a single bond, and a second polycyclic aromatic hydrocarbon to which a second substituent R2 other than a hydrogen atom is bonded by a single bond,
• wherein the first polycyclic aromatic hydrocarbon and the second polycyclic aromatic hydrocarbon are formed from the same polycyclic aromatic hydrocarbon,
• wherein a binding site of the first substituent R1 to the first polycyclic aromatic hydrocarbon is the same as a binding site of the second substituent R2 to the second polycyclic aromatic hydrocarbon, and
• wherein the first substituent R1 and the second substituent R2 are different.

A method for manufacturing an electronic device, the electronic device including at least

• a first electrode,
• a second electrode disposed separately from the first electrode, and
• an active layer provided from the first electrode to the second electrode,
• the method comprising:
• forming the active layer by coating and drying
• a mixed solution formed from a mixture of a first polycyclic aromatic hydrocarbon to which a substituent R1 other than a hydrogen atom is bonded by a single bond and a second polycyclic aromatic hydrocarbon, or
• a mixed solution formed from a mixture of a first polycyclic aromatic hydrocarbon to which a first substituent R1 other than a hydrogen atom is bonded by a single bond and a second polycyclic aromatic hydrocarbon to which a second substituent R2 other than a hydrogen atom is bonded by a single bond,
• wherein the first polycyclic aromatic hydrocarbon and the second polycyclic aromatic hydrocarbon are formed from the same polycyclic aromatic hydrocarbon, and
• wherein a binding site of the first substituent R1 to the first polycyclic aromatic hydrocarbon is different to a binding site of the second substituent R2 to the second polycyclic aromatic hydrocarbon, or
• a mixed solution formed from a mixture of a first polycyclic aromatic hydrocarbon to which a first substituent R1 other than a hydrogen atom is bonded by a single bond and a second polycyclic aromatic hydrocarbon to which a second substituent R2 other than a hydrogen atom is bonded by a single bond,
• wherein the first polycyclic aromatic hydrocarbon and the second polycyclic aromatic hydrocarbon are formed from the same polycyclic aromatic hydrocarbon,
• wherein a binding site of the first substituent R1 to the first polycyclic aromatic hydrocarbon is the same as a binding site of the second substituent R2 to the second polycyclic aromatic hydrocarbon, and
• wherein the first substituent R1 and the second substituent R2 are different.
