The rare earth complex of 67.9% is in the channel, suggesting that the assembly of the complex molecular on the mesoporous MCM-41 was carried out mainly in the channel.展开更多

These complexes were characterized by elemental analysis, conductivity measurements and IR spectroscopy. Spectrographic analyses suggest that the complexes show a similar coordination mode. At the same time, the luminescence properties of the Eu(III) and Tb(III) complexes were also studied.展开更多
