摘要

The influence of structure of the phosphine oxide ligands on stability of their complexes was studied by spectroscopic techniques. Surprising the electron donating methyl groups at phenyl rings of phosphine oxide groups lead to decrease of the stability of europium complex comparing with ubsubsituted one due to their sterical prevention of conjugation between phenyl rings and P=O-groups.. This unusual behavior was first time demonstrated by spectroscopic titration and Job's plot analysis.
