“…The quantum yield of the solid-state sample of 5 is determined to be 21%. The solid-state sample of complex 1 displays a much higher quantum yield of around 44%, which is higher than that of many terbium-containing complexes, [63][64][65][66][67][68][69][70][71][72][73][74] even though lower than that of some others. 75 Therefore, complex 1 has better photoluminescence performance than complex 5.…”

Two structural series, including two isomorphous homodinuclear complexes Ln(2)(H(2)O)(4)(C(6)NO(2)H(4))(6) (Ln = Tb (1) and Er (2)) and four isostructural one-dimensional (1-D) chain-like assemblies [Ln(H(2)O)(4)(C(6)NO(2)H(4))(2)](n) x nCl (Ln = Sm (3), Eu (4), Tb (5), and Dy (6)), have been rationally prepared through a facile ultrasonic synthesis and have been characterized by X-ray diffraction and photophysical measurements. Both complexes, 1 and 2, feature a homodinuclear structure, based on two 8-fold coordination lanthanide atoms bridged by four nicotinic acid ligands. Complexes 3-6 are characterized by a 1-D polycationic chain-like structure, containing eight-coordinated lanthanide ions and bridging isonicotinic acid ligands. The 1-D polycationic chains and the isolated chloride anions are interconnected via hydrogen bonds and pi-pi interactions to form a three-dimensional supramolecular network. The effect of nicotinic/isonicotinic acid ligands on the structures and the photoluminescence properties, as well as the relationship between the photoluminescence properties and the structures, was investigated based on IR, UV-vis absorption spectra, low temperature phosphorescent spectra, excitation, and emission spectra. The fluorescence quantum yields of complexes 1 and 2 were determined to be 44% and 21%, respectively.

“…In order to enhance luminescence intensity or lifetime of rare earth ions and to expand the range of luminescence, some synergetic organic agents called as "antennas effect" 5 are employed to form rare earth coordination complexes. [6][7][8][9][10] These ligands have abilities of absorbing and transferring energy efficiently to the rare earth ions (intra-molecular energy transfer) in rare earth complexes, resulting in the increased luminescence intensity of rare earth ions. Except for organic ligands as "antennas" to sensitize rare earth ions, some metal ions involved in heterometallic complexes can be as sensitizers on the luminescence of Ln(III).…”

Samnium(III)-bismuth(III) heterobimetallic complexes, SmBi(edta)(NO 3 ) 2 •7H 2 O (1) and SmBi(dtpa)(NO 3 )• 3.5H 2 O(2) (edta=ethylenediaminetetraacetate, dtpa=diethylenetriaminepentaacetate), were synthesized and characterized by means of X-ray single crystal diffraction, X-ray powder diffraction, elemental analysis, ICP, FT-IR spectra and thermal analysis. The structure analysis revealed that 1 is in crystalline and 2 is in non-crystal state. Complex 1 crystallizes in monoclinic, space group P2 (1) tween Bi(III) atoms and Sm(III) atoms result into infinite 3D network structure. Thermal decomposition of the two complexes proceeds in similar stages, i.e., dehydration, pyrolysis of ligand, and decomposition of salt, and the final residue is oxide. In addition, the spectral properties have been studied through FL spectra and UV-Vis DRS. The two complexes exhibit one broad band Bi 6s6p-6s 2 emission under UV excitation and the characteristic Sm 3+ ion 4 G 5/2 → 6 H J/2 (J＝5, 7, 9, 11) transitions under visible light excitation, respectively.

“…Now the key question is how to make the structure novel and innovative, which requires that the second ligand joins into the coordination compounds. The second ligand will make the structure very rich and colorful [18][19][20][21]. The second ligand can change the zero-dimension into one-dimension or one-dimension chain into two-dimension layered structure by the second ligand functioning as the bridge.…”
