Effects of fluorophore substituents on the properties of ruthenium-based fluorescent probe for detection ethylene gas

Ethylene is a crucial compound extensively utilized across various fields, including industry, agriculture, and ecology. Given its significance, developing a simple and rapid method for detecting ethylene is essential. The first-generation Grubbs catalyst (G-1) was used as a quencher to bind small molecule fluorophores in this study. The synthesized probe was used to detect ethylene based on the olefin metathesis. This method has the advantages of mild reaction conditions and a wide range of functional groups. Based on the above principle, we thoroughly investigated the impact of different substituents on the probe’s detection performance, aiming to inform subsequent modifications of the fluorophore. Overall, our findings propose strategies for optimizing the molecular structure of fluorophores, enabling researchers to enhance ethylene quantification methods across diverse applications.
