Microporous chiral metal coordination polymers: hydrothermal synthesis, channel engineering and stability of lanthanide tartrates.
نویسندگان
چکیده
L-Tartrate ions can endure hydrothermal conditions up to 160 degrees C to form the robust, enantiopure open-framework coordination polymers [Ln2(L-TAR)3(H2O)2]3H2O, 1; the addition of succinate results in formation of the related [Ln2(L-TAR)2(SUC)(H2O)2]5.5H2O, with larger channels than , whereas racemic D/L-tartrate gives the more condensed [Ln2(D/L-TAR)3(H2O)2], . TAR = [C4H4O6]2-.

متن کاملNano-sized AlPO4-5 Crystals: Synthesis and characterization
Molecular sieves and zeolites are materials whose crystalline frameworks form nanometer or subnanometer pores. A variety of different crystal structures are known having a range of pore sizes. Because the pore sizes are usually smaller than 2 nm, they are classified as microporous materials. Synthesis of microporous materials is usually conducted by the high temperature treatment (80-200 °C) of...
