ORGANIC SEMICONDUCTOR MATERIAL, AND LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, LIGHTING SYSTEM AND ELECTRONIC DEVICE, EACH USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new material having a bipolar property, and to decrease power consumption of light-emitting elements, light-emitting devices and electronic devices.

SOLUTION: The power consumption of light-emitting elements, light-emitting devices and electronic devices can be decreased by using a material provided by bonding a skeleton having an electron transport property and a skeleton having a hole transport property through a twisted quaterphenylene structure (preferably [1,1':2', 1'':2'', 1''']quaterphenyl-4-4'''-diyl) hard in expanding conjugation.
