Abstract:
An electroluminescence material comprising one or more polymers which comprise structural units of the formula (I), ##STR1## where the symbols and indices have the following meanings: Ar.sup.1, Ar.sup.2, Ar.sup.3, Ar.sup.4, Ar.sup.5, Ar.sup.6 are identical or different, monocyclic and/or polycyclic aryl and/or heteroaryl groups which may be linked via one or more bridges and/or be condensed and may be unsubstituted or substituted, where Ar.sup.1, Ar.sup.3, Ar.sup.5 and Ar.sup.6 are each divalent and Ar.sup.2 and Ar.sup.4 are each monovalent; R.sup.1 is H, a hydrocarbon radical having from 1 to 22 carbon atoms, which may be unsubstituted or substituted, preferably by F, and can also contain heteroatoms, preferably 0, or Ar.sup.7, where Ar.sup.7 is, independently of Ar.sup.1-6, as defined for Ar.sup.1-6 ; n is 0, 1 or 2. The electroluminescence material of the invention has, inter alia, a low threshold voltage of the electroluminescence and a high efficiency, although the polymers are not conjugated.
Abstract:
High molecular linear, thermoplastic, epoxide-amine-adducts containing the structural segment ##STR1## are prepared by a solvent-free reaction of equivalent amounts at 20 to 200.degree. C. of N,N'-bis(aralkyl) diamines (for example, N,N'-dibenzyl-ethylenediamine, N,N'-dibenzyl-p-xylylenediamine, N,N'-dibenzyl-4,4'-diamino-diphenylmethane, N,N'-dibenzyl-3,6-dioxa-octanediamine-1,8) with diepoxides (for example, 2,2-bis(4-glycidyloxyphenyl)propane). The polyadducts are soluble and may be processed by thermoplastic methods. The polyaddition process may be conducted for the forming of shaped objects in a form-shaping vessel, for the production of coatings directly upon the surface to be coated and also in the presence of inserted materials and has, due to these characteristics, the nature of a casting system.
