基于镧系金属配合物Eu(DBM)3Phen杂化微球的合成及其荧光传感性能
Synthesis and fluorescence sensing properties of Eu(DBM)3Phen hybrid microspheres based on lanthanide metal complex
摘要
Abstract
A fluorescent microsphere lomefloxacin hydrochloride(LOM)hybridization prob,that can be used for the detection of the antibiotic lomefloxacin hydrochloride in the aqueous environments,has been designed and synthesized by complexing SiO2 with the lanthanide metal complex Eu(DBM)3Phen using the seed growth method.Under the conditions of selecting dibenzoylmethane(DBM)and 1,10-phenanthroline(Phen)as the functional ligands,tetraethyl orthosilicate(TEOS)as the silicon source,ammonia as the catalyst,and cetyltrimethylammonium bromide(CTAB)as the linker,a kind of SiO2@Eu(DBM)3Phen hybrid microsphere with an average size of 200 nm nanometers was obtained.The probe's structure and properties were systematically characterized by X-ray diffractometer(XRD),Fourier transform infrared spectrometer(FT-IR),and its fluorescence enhancement performance was further investigated.Results showed that the introduction of SiO2 effectively improved the fluorescence intensity of Eu(DBM)3Phen.Meanwhile,sensing detection tests for different LOM concentrations yielded a linear calibration curve:Meanwhile,the sensing detection experiments were carried out on different concentrations of LOM,and linear fitting curves were obtained.When the concentration of LOM is 40-800 μmol/L,the peak value corresponding to the responsive fluorescent monomer of hybridized probe SiO2@Eu(DBM)3Phen are significantly enhanced.关键词
