Abstract：A novel ligand (L) and its corresponding complexes Na2 EuLCl5 · 4H2 O and Na2 TbLCl5 · 4H2 O ,were prepared and characterized .The thermogravimetric analysis shows the two complexes have good thermal stabilities with decomposition temperatures 373 and 385 ℃ ,respectively .The luminescence spectra showed that the ligand L was an efficient sensitizer for Eu(Ⅲ)and Tb(Ⅲ)luminescence .The UV‐vis absorbance and the Stern‐Volmer analysis indicate that the main quenching mechanism is a static quenching procedure .The binding constants ,binding site number at different temperatures were calculated by Van't Hoff equation ,w hich confirms that the Van der Waals and hydrogen bond interactions are mainly impulse to the formation of complexes BSA‐L coordination compound .
