摘要: Abstract Hydrothermal reactions of lanthanide(III) oxide, isonicotinic acid, methanoic acid at 170 °C lead to two new lanthanide carbonate frameworks[Ln(IN)(CO3)(H2O)] (Ln La (1), Eu (2); HIN acid). Compounds 1 and 2 feature a two-dimensional (2D) architecture constructed by the intergrowth infinite layers. The enhanced fluorescence intensity indicates effective energy transfer from ligand Eu3+ center.
