  • Hole transport materials
    Patent number: 9954174
    Abstract: There is provided a copolymer having Formula I In Formula I: A is a monomeric unit containing at least one triarylamine group; B? is a monomeric unit having at least three points of attachment in the copolymer; C? is an aromatic monomeric unit or a deuterated analog thereof; E is the same or different at each occurrence and can be H, D, halide, alkyl, silyl, germyl, aryl, arylamino, siloxane, a crosslinkable group, deuterated alkyl, deuterated silyl, deuterated germyl, deuterated aryl, deuterated arylamino, deuterated siloxane, or a deuterated crosslinkable group; a, b, and c are the same or different and are mole fractions, such that a+b+c=1, and a and b are non-zero.

  • Hole transport materials
    Patent number: 9525134
    Abstract: There is provided a hole transport compound having Formula I In Formula I: Ar1-Ar3 are selected from the group consisting of aryl groups and deuterated aryl groups; with the proviso that Ar1 is not the same as Ar2, E is the same or different at each occurrence, and n is an integer greater than or equal to 1. There is also a hole transport compound having Formula II In Formula II: Ar4-Ar7 are the same or different and are aryl groups or deuterated aryl groups; E1 is the same or different at each occurrence; R1-R5 are the same or different at each occurrence; a-e are the same or different and are in integer from 0-4; m is an integer from 0-6; o is an integer greater than or equal to 1. There is also provided an organic electronic device.
