Synthesis,Characterization, and Luminescence Properties of a Multi-benzoic Acid Rare Earth Complex Applied to Fluorescence Nanometer and Micrometer Fiber

The design and synthesis of a novel multi-benzoic acid ligand and the luminescence properties of the rare earth complex with the ligand and Eu3 ＋were focused on. The composition and structure of ligand and complex were characterized by Fourier transform infrared（ FT-IR） spectroscopy,1H nuclear magnetic resonance（1H NMR） techniques, and element analysis. The luminescent properties,heat resistant performance,morphology and distribution in fibers of the complex were also measured. The fluorescent spectra indicate that as-synthesized complex owns excellent luminescent properties. The maximum relative fluorescence intensity of the complex is more than 7 000. The thermo-gravimetric analysis（ TGA） results confirm that the initial degradation temperature of as-synthesized complex is at 413 ℃. Transmission electron microscope（ TEM） and field-emission scanning electron microscope（ FESEM） photos show that the particle size of assynthesized complex is 50-60 nm,and can be uniformly distributed in fiber. Based on these results, it can be concluded that the synthesized complex has excellent luminescent properties, good thermal stability,and extensively application prospect.

Preparation and Properties of Poly (ethylene terephthalate) Luminescence Fibers with Multi-branched Benzoic Acid Rare Earth Complex

A new multi-branched benzoic acid rare earth complex( MBBAL-Eu( III) complex) was prepared. The advanced tested technologies were employed to characterize the composition and structure of as-prepared complex. Scanning electron microscopy( SEM) image shows that as-prepared complex has a layer structure. Transmission electron microscopy( TEM) image presents that the shape of MBBAL-Eu( III) complex is similar to oval; the size is in the range of 20-50 nm. The thermogravimetric analysis( TGA) curves of MBBAL-Eu( III) complex reveal that as-prepared complex has good thermal stability. The PET luminescence fibers with MBBAL-Eu( III) complex were prepared through meltspinning and electrospun methods. The results prove that asprepared fibers with MBBAL-Eu( III) complex have good luminescent properties and show bright red light.
