Synthesis and structural characterization Novel luminescent heterobimetallic Ln–Cu(I) 3D coordination polymers based on 5-(4-pyridyl) isophthalic acid as heteroleptic ligand. Synthesis and structural characterization](/preview/png/1301320.png)
• Six novel, isomorphic, Ln-Cu(I) coordination polymers based on an N/O mixed ligand were synthesized.
• First association of above lanthanides with Cu(I) in heterobimetallic 3D coordination polymers is reported
• Upon excitation compounds 3–5 show remarkable photoluminescence of warm white, cool white and light blue
• Color of the light emitted depends on the nature of the lanthanide ion, a key factor for advanced applications of 3–5.
Six novel photoluminescent Ln–Cu(I) heterobimetallic 3D coordination polymers, [LnCu (pyip2 −)2(H2O)]n (1–6) (where Ln is Pr, Nd, Sm, Eu, Gd, Ho, respectively, and H2pyip = 5-(4-pyridyl) isophthalic acid) have been synthesized in a concise and reproducible manner under hydrothermal conditions. All of these substances were fully characterized by appropriate spectroscopic methods and elemental analysis. Structural determinations revealed that 1–6 are isomorphic and display 3D frameworks. Luminescent properties of the obtained compounds have been studied in detail revealing light emissions of warm white, cool white and light blue for 3, 4 and 5, respectively. The effectiveness of association of a rare earth with a transition metal in producing valuable luminescent materials for practical applications is demonstrated.
Six novel coordination polymers namely [LnCu (pyip2 −)2(H2O)]n (Ln = Pr, Nd, Sm, Eu, Gd, Ho); (H2pyip = 5-(4-pyridyl) isophthalic acid) have been synthesized and their luminescent properties explored.Figure optionsDownload as PowerPoint slide
