Structure and luminescent property of a Sm3+ complex containing benzoyltrifluoroacetone and 1,2-bis[(anthracen-9-ylmethyl)amino]ethane ligands

The synthesis, structure, and luminescent propertiesof a samarium(III) complex (A2) containing benzoyltrifluoroacetone (HTFPB) 1,2-bis[(anthracen-9-ylmethyl)amino]ethane (BAAE2) ligands are herein reported. structure of A2 has been elucidated by infrared spectroscopy single crystal X-ray diffraction. crystallographic analysis demonstrated that mononuclear with formula Sm(TFPB)3(BAAE2) in which Sm3+ ion is coordinated to six O-atoms from three TFPB two N-atoms one ancillary ligand (BAAE2). UV-Vis data show strongly absorbs the region 220-400 nm. Nonetheless, gives poor emission due quenching effect anthracenyl moiety.
