Selective Ammonia Sensing through Reversible Vapochromism and Luminescence ON-OFF Switching of a Chalcone-Based Co(II) Complex

Key Points

To investigate the ammonia sensing capabilities of a chalcone-based cobalt(II) complex through vapochromism and luminescence changes.
Synthesis of a chalcone-based cobalt(II) complex
Exposure of the complex to ammonia vapor
Observation of vapochromic and luminescent properties during gas exposure
Distinct color change observed upon ammonia exposure indicating vapochromism
Reversible luminescence ON-OFF switching with repeated exposure
Demonstrated potential for real-time ammonia detection applications

Abstract

In this work, we demonstrate that a chalcone-based cobalt(II) complex exhibits distinct vapochromism upon exposure to ammonia (NH 3 ) vapor, accompanied by reversible luminescence ON-OFF switching. The response is triggered by...
