Abstract[English]
The present invention relates to light emitting pyridinium salts and synthesis thereof. The synthesis encompases the formation of the pyridine luminophores, their alkylation, an optional ion exchange sequence and purification. The present invention also relates to the application of the light emitting pyridinium salts, for example in light emitting electrochemical cells (LEC).[French]
