The research of controllability of the framework of carboxylic acid rare earth complexes and their performance construction fundamentallyt promotes the further research of high performance carboxylic acid rare earth complexes.The reasearch is conducted as follows: First, the precursor compounds of mixed rare earth nitrates, dibenzoylmethane and dibenzyl sulphoxide is synthetically formed through hot reaction of dissolvent.Next,the polycyclic carboxylic acid is induced with supersonic micro-bubles to replace the nitrate ions contained in the precursor compounds. Then, the synthesis of complexes in bidentate chelating coordination mode rather than in bidentate bridging coordination mode could be promised by the combination of the larger spatial steric hindrance caused by the ligands contained in the precursor compounds with supersonic micro-bubles shear on the bridged coordination of carboxyl. Finally, the molecular (the mononuclear complex, the binuclear complex, the polynuclear complex) formation of the complexes is contolled through supersonic micro-buble shear and other relavant factors. As a result, the spatial demesion of the complexes is optimized and higher performance is constructed.The research constructs a reaction model by initially adopting the way of inducing carboxyl with supersonic bubles to replace the ions of micro-molecules in the precursor compouds, revealing the laws of its shear reaction of bridged coordination of carboxyl.The research makes a further exploitation of the controllability of the construction of the structure and performance of rare earth complexes with the purpose of solving the issue of low luminous efficiency and providing a new idea for the research in this field.
