The present invention relates to Formula (I) complexes of cobaltocations with dicyanoborate or tricyanoborate counter anions. The complexes are used as redox active species or dopant for hole transport materials in electrochemical and/or optoelectronic devices. The present invention relates additionally to electrolyte formulations comprising such salts. in which Xis H orF, Y 1 and Y 2 are each independently C or N, z is 1 or 2, n is 2 or 3, The other variables are as defined in the claims. |
