This study presents a detailed photophysical analysis of purine-based derivatives' complexation processes in polar solvents and aqueous media for chemical sensors. Various characterization techniques, including steady-state absorption, fluorescence, and time-resolved fluorescence spectroscopy, were employed. Several sensor prototypes were demonstrated for detecting metal ions such as alkali, alkaline earth, heavy, and transition metals, applicable in industry (using acetonitrile) and biology/environment (using water). The synthesized compounds detected traces of transition and heavy metal ions at ppb levels. New water-soluble compounds ZiK-740 and ZiK-772 exhibited high sensitivity to mercury (II) ions in water.
