摘要

Luminescent rare earth coordination polymers [H2NMe2](3)[Y(DPA)(3)] ([H2NMe2](+) = dimethyl amino cation; H(2)DPA = 2,6-dipicolinic acid) are synthesized and is further modified by the ionic exchange reaction of [H2NMe2](+) cation with rare earth ions, which is named as RE3+ aS, [Y(DPA)(3)] (RE = Eu, Tb, Sm, Dy) hybrid systems. The multi-color can be tuned for these functionalized hybrid systems and even white color luminescence can be integrated for Sm3+ aS, [Y(DPA)(3)]. Besides, the fluorescent sensing property of Tb3+ aS, [Y(DPA)(3)] system is checked, which shows high selectivity towards Cr3+ with the concentration of 10(-5) molai...L-1.
