Abstract

This invention presents, firstly, the principle that simple and known emitter materials which are uncharged per se, as known, for example, from OLED technology, can be converted to a charged species by the introduction of a charged imidazolinium radical. This charged species can then be used in organic light-emitting electrochemical cells.
