Abstract
The invention relates to electrochemical devices comprising complexes of cobalt comprising at least one ligand with a 5- or six membered, N-containing heteroring. The complex are useful as p- and n-dopants, as over of electrochemical devices, in particular in organic semiconductors. The complexes are further useful as over-discharge prevention and overvoltage protection agents.
