Abstract

A K type of copolyarylborane:wherein hydrogen atoms are bonded to the ends; Arn represents at least one of Ar1, Ar2, and Ar3; each of Ar1 and Ar2 represents an arylene radical; Ar3 represents an heteroaromatic arylene radical; Ar1 has a π electron density of no less than that of benzene; Ar2 is capable of hole transport; Ar3 has a π electron density of no greater than that of benzene and less than that of Ar1; x, y, and z respectively represent the molar parts of Ar1, Ar2, and Ar3; each of x, y, and z is in the range of 0-1, and x+y+z=1; and R represents an aryl radical. This K type of copolyarylborane may be of use for organic light-emitting diodes (OLEDs), organic solar cells, organic photodetectors, and organic field-effect transistors.
