To provide nitrogen-containing aromatic compounds with excellent oxygen reduction activity, metal complexes containing them, and catalysts and electrodes employing the same, the present invention provides an aromatic compound satisfying the following conditions (a) and (b):

Nitrogen-containing aromatic compounds and metal complexes

A polymer containing at least one unit of formula is prepared by treating a compound of formula wherein Yis I, Br, Cl or O&#x2014;S(O)CF,with an S-donor agent, in order to obtain the compound of formula wherein Yis as defined for the compound of formula (5).

Preparation of polymers comprising at least one benzo[c][1,2,5]thiadiazol-5,6-dicarbonitrile-unit

The present invention relates to polymers comprising repeating unit(s) of the formula (I), and their use in electronic devices. The polymers according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high charge carrier mobilities and high temperature stability of the emission color are observed, if the polymers according to the invention are used in polymer light emitting diodes (PLEDs).
