- Fluorescent probe ruthenium complex, synthesis method and application thereof
-
The invention discloses a fluorescent probe ruthenium complex, a synthesis method and the application thereof. The complex is obtained by coordination of 5-formyl-1,10-o-phenanthroline as a ligand andruthenium ions. A strong electron-withdrawing formyl is introduced to the 5th site of o-phenanthroline, which coordinates with the metallic ruthenium to obtain a hexa-coordinate ruthenium complex serving as a fluorescent probe for detecting cysteine and homocysteine, wherein the probe shows high sensitivity and high selectivity recognition on the cysteine and the homocysteine. In the presence ofother interfering substances, the fluorescence intensity is not changed significantly, and the probe shows strong interference capability. The probe has fast response and wide pH application range, does not require an organic solvent, and is a ruthenium complex fluorescent probe for detecting cysteine and homocysteine in a 100% aqueous phase.

- Organic complex mercury ion probe and preparation method and application thereof
-
The invention discloses an organic complex mercury ion probe and a preparation method and application thereof. The preparation method comprises the steps of enabling rhodamine B to react with hydrazine hydrate to obtain pink solid rhodamine B hydrazide, and enabling 5-methyl phenanthroline to react with selenium dioxide to obtain 5-formyl phenanthroline; enabling a reaction product obtained by reacting the rhodamine B hydrazide and the 5-formyl phenanthroline to react with Ir2(ppy)4Cl2, and then reacting with NH4PF6, thus finally obtain the organic complex mercury ion probe. The preparation method of the probe is simple, and has the advantages of stable light emission, convenient and efficient operation and suitability for qualitatively, quantitatively and quickly detecting mercury ions in a solution, soil, biological cells and the like, and can be widely applied to the fields such as environment detection and biological cell imaging.
