  • Spectroscopic characterization of the platinum(II) complex.
  • Investigation of the complex's response to various metal ions, including Mg2+, using UV-Vis absorption and fluorescence spectroscopy.

    • Main Results:

    • The synthesized platinum(II) complex selectively binds to magnesium ions (Mg2+).
    • Complexation with Mg2+ results in distinct and significant changes in the complex's color.
    • Luminescence intensity of the complex is markedly altered upon binding with Mg2+, enabling sensitive detection.

    Conclusions:

    • A novel platinum(II) bipyridyl acetylide complex with a monoazacrown moiety acts as an effective chemosensor for Mg2+.
    • The chemosensor exhibits high selectivity and sensitivity for magnesium ion detection.
    • The observed colorimetric and luminescent responses provide a robust platform for signaling Mg2+ presence.
