Abstract

The invention concerns nitrogenous polymers containing structural units of formula (I), wherein the symbols and indices have the following meanings: Ar?1, Ar2 and Ar3¿ are identical or different and designate mono and/or polynuclear aryl and/or heteroaryl groups, or carbon atoms, which are optionally linked via one or a plurality of bridges and/or condensed, it further being possible for these groups to be optionally substituted; X is a single bond, -O-, -S-, -SO-, -SO¿2?-, NR?3, -CR4R5¿-, -CO-, -CR?6=CR7, CR8R9-CR10R11 or SiR12R13; R1-R13¿ are identical or different and designate H, a hydrocarbon residue with 1 to 22 carbon atoms or Ar4, where Ar4 is the same as or different from Ar1 and has the same meanings as Ar1; and n is 1, 2 or 3.
