Two novel luminescent lanthanide sulfate-carboxylates with an unusual 2-D bamboo-raft-like structure based on the linkages of left- and right-handed helical tubes involving in situ decarboxylation

摘要

Two novel 2-D bamboo-raft-like lanthanide luminescent materials [Ln(Himc)(SO4)(H2O)](L-n=Dy, Eu; H(2)imc=4-imidazolecarboxylic acid), constructed from alternate left- and right-handed helical tubes, were synthesized and characterized; interestingly, H(2)imc came from the in situ decarboxylation of the 4,5-imidazoledicarboxylic acid (H(3)imdc) in the hydrothermal reactions.
