Bis-chalcone Fluorescent Probe for Hydrazine Ratio Sensing in Environment and Organism.

In this paper, four novel hydrazine fluorescent probes X-X with bis-chalcone structure were designed and synthesized. Through the measurement of its optical properties, it is found that it can quickly identify hydrazine, high sensitivity, low detection limit, and good anti-interference ability. The recognition of hydrazine by probes X-X is not affected in the pH range of 4-10, X has the highest sensitivity, and the detection limit is as low as 0.

Novel Bis-pyrazoline Fluorescent Probe for Cu and Fe Detection and Application in Cell Imaging.

A fluorescent probe Y((1,1'-([1,1'-biphenyl]-4,4'-diylbis(3-(2-hydroxyphenyl)-4,5-dihydro-1H-pyrazole-5,1-diyl)) bis(ethan-1-one))) was designed and synthesized, which could be used to Cu and Fe sensors. Through the study of optical properties, the probe Y shows good selectivity and sensitivity to Cu and Fe in aqueous tetrahydrofuran solution [10.0 mM HEPES, pH 7.
