Novel materials based on lanthanide complexes with six pyrazolecarboxylates were obtained. They possess high solubility due to the purposeful introduction of the nitrogen heteroatom in α-position to the carboxy-group, and their luminescence quantum yields reach 100%. High absorption and non-toxicity allowed their successful use for bioimaging in cellulo. While the special approach to electron transport enhancement allowed using them as OLED emission materials.
