Study on Preparations and Fluorescent Properties of Rare Earth Complex with Property of Fluorescence Sensor
Europium chloride, 2-thienylformyltrifluoroacetone and sodium silicate were used to synthesize new-style rare earth complex (Eu-TNS). By adding into dichloromethane solution containing Eu-TNS, the fluorescent intensities were enhanced gradually and regularly. High-resolution mass spectrometry was used to detect the formula of Eu-TNS, which belongs to multi-core rare-earth complex. Polarity of solution increasing by adding absolute ethanol will cause Eu-TNS to dissociate, which enhances the fluoresceot intensities of Eu-TNS solution. This rare earth complex Eu-TNS can be employed as fluorescence sensor to detect the content of ethanol in organic solvent.
