Abstract
An organic electronic material including a charge transporting polymer having a structure that is represented by Formula (1) and that is branched in three or more directions (in the formula, Rf's are each independently a fluoroalkyl group, a and b are 0 or 1, and a and b are not both 0 at the same time).
Claims17
An organic electronic material comprising:
- a charge transporting polymer having a structure branched in three or more directions,
- wherein the charge transporting polymer comprises a trivalent or higher-valent structural unit, a divalent structural unit comprising a structural unit L1 having a structure represented by Formula (1) below, and a monovalent structural unit comprising a structural unit T1 having a structure represented by Formula (4-4) below,
- in Formula (1), Rf's are each independently a fluoroalkyl group, a and b are 0 or 1, and a and b are not both 0 at the same time,
- —Ar—O—(CH2)n —Z (4-4)
- in Formula (4-4), Ar is an arylene group or a heteroarylene group, n is 1 to 4, and Z is a polymerizable functional group.
