Smart NIR‐Emitting Organometallo Pt(II)‐Ionosilica Aerogel for Selective Au(III) Sensing and Recovery
, as evidenced by emission quenching. Experimental and theoretical studies point to an unprecedented Pt(II)···Au(III) metallophilic interaction, shedding light on the gold adsorption mechanism. Remarkably, the material fully restores its luminescent properties upon removal of gold species, enabling multiple sensing and recovery cycles, thus enhancing practical applicability. This study introduces a multifunctional hybrid platform that integrates optical functionality, structural robustness, and metal selectivity, expanding the application of smart aerogels in sustainable sensing and resource recovery.
