摘要: Abstract A series of one-dimensional coordination polymers assembled from LnNO3 · 6H2O (Ln = Sm(1), Eu(2), Tb(3), La(4), Ce(5), Pr(6), Nd(7), Dy(8)), quinoline-2,3-dicarboxylic acid (2,3-H2qldc) and 1,10-phenanthroline (phen) formulated as [Ln(2,3-qldc)(3-qlc)(phen)]n (3-Hqlc = quinoline-3-carboxylic acid) were obtained under hydrothermal conditions. It is remarkable that in situ decarboxylation was observed during preparing these polymers. Complexes 1–8 characterized by elemental analyses, IR spectroscopy single crystal X-ray diffraction analyses. The thermal stabilities photoluminescence properties complexes have been investigated.
