A series of water-soluble helicene dyes generating intense electrochemiluminescence (ECL) signal in physiological conditions is reported. Those species were prepared using diaza [4] and [6]helicenes as structural cores modified with sulfonate groups in various positions. Such functional groups improve their water solubility and induce a red-shifted emission. Efficient ECL emission up to the near-infrared is achieved in water.
