A series of model compounds and heptadentate neutral phosphorus-containing podands that differ in the conformational rigidity of the terminal groups and in the coordination properties of the phosphoryl groups were synthesized. The thermodynamic parameters of complexation and the cationic selectivity of organophosphorus compounds and podands with respect to LiNCS and NaNCS were studied by calorimetric
合成了一系列模型化合物和七齿中性含
磷podands,它们的末端基团的构象刚性和
磷酰基的配位性质不同。通过在 298 K 的
乙腈中量热滴定研究了有机
磷化合物和 podands 对 Li
NCS 和 Na
NCS 的络合热力学参数和阳离子选择性。讨论了某些含
磷 podands 对 Li+ 阳离子具有高选择性的原因。
