1,3,5,7-Tetramethylcyclotetrasiloxane Fluorescent Probe for Ciprofloxacin and Its Application in Iron Ion Detection

Abstract

The invention discloses a 3,5,7-trimethylcyclotetrasiloxane ciprofloxacin fluorescent probe for detecting ferric ions. 1,3,5,7‑Tetramethylcyclotetrasiloxane modified ciprofloxacin has bright green fluorescence, and the Fe 3+ When the ions appear, the fluorescence is quenched, so that the Fe 3+ detection. The structural formula of 1,3,5,7-tetramethylcyclotetrasiloxane ciprofloxacin fluorescent probe is: the fluorescent probe provided by the present invention has higher sensitivity when detecting iron ions, and is resistant to other metal ions ability to interfere with the Fe 3+ Good selectivity and low detection limit.

Description

Fluorescent probe of 1,3,5,7-tetramethylcyclotetrasiloxane ciprofloxacin and its application in iron ionization Applications in sub-detection technical field The present invention relates to fluorescent sensing technical field, be specifically related to a kind of fluorescent probe and its application in iron ion detection use. Background technique Iron is an indispensable trace element in the human body and an important component of hemoglobin, which is The life body undertakes the function of transporting oxygen. In addition, iron is involved in the formation of various immune systems and enzymes in the human body. in vivo The lack of iron can cause iron deficiency anemia, insufficient cell supply, human fatigue and fatigue, and at the same time, it will lead to the decline of human immunity. drop. Iron deficiency in childhood will affect children's mental activity and intellectual development, and the process is irreversible. Iron in human body Iron overlo...
