1D lanthanide coordination polymers containing biphosphonate ligand: Synthesis, structures and luminescence properties

S-Heptazine N-ligand based luminescent coordination materials: synthesis, structural and luminescent studies of lanthanide–cyamelurate networks

“…The Sm 3+ ion is well known for its high emission intensity, 74 and is also often employed as an emissive dopant, 75 but it has also been incorporated as building blocks of emissive coordination polymers. 76,77 The Sm– Cy network at 298 K exhibits the characteristic reddish emission of the Sm 3+ ions. An excitation band located at 300 nm is measured, which is reminiscent of the Cy ligand absorption, leading to the conclusion that Cy acts as an antenna.…”
