Abstract

Two novel rare earth complexes with curcumin and pyridine have been synthesized and characterized by elemental analysis , FT-IR , 1H-NMR , MS spectroscopy , and thermogravimetric ( TG ) analysis. The photophysical properties were studied both experimentally and theoretically. The results suggest that the obtained two complexes exhibited obvious two- photon absorption in the range 700–860 nm in DMSO solution, and that presented a significant enhancement of single-/two- photon excited fluorescence and TPA cross section values compared with the free ligand . Additionally, two- photon microscopy fluorescent imaging of MCF-7 cells labeled with the title complexes revealed their potential application as a biological fluorescent probe .
