Thin Films of Highly Luminescent Lanthanide Complexes Covalently Linked to an Organic−Inorganic Hybrid Material via 2-Substituted Imidazo[4,5-f]-1,10-phenanthroline Groups

“…1 H NMR spectra were recorded on a Bruker Avance 300 spectrometer (300 MHz). 13 C NMR spectra were recorded on a Bruker AMX 400 (100 MHz). Mass spectra were taken on a Thermo Finnigan LCQ Advantage mass spectrometer.…”

“…[1][2][3][4][5][6][7][8][9] In addition, the ligands expel water from the first coordination sphere, which can cause radiationless deactivation. 10,11 To explore the potential of the complexes for photonic applications (light-converting devices), [12][13][14][15][16][17] it is useful to incorporate the complexes in an inert host matrix. [18][19][20][21][22][23][24][25][26][27] A problem often encountered upon embedding of the luminescent complexes in the host matrix is the nonhomogeneous distribution of the compounds, 28,29 which leads to clustering of lanthanide ions and hence a decrease of the luminescence intensity.…”

Ionic liquid as plasticizer for europium(iii)-doped luminescent poly(methyl methacrylate) films

“…[1][2][3][4][5][6][7] Processable lanthanide-based luminescent molecular materials can be obtained by doping the lanthanide(III) complex in a polymer matrix. 8,9 Typical applications of such polymer films are in organic light emitting diodes (OLEDs) [10][11][12][13][14] or in active optical polymer fibers for data transmission. [15][16][17] A popular polymer matrix for use as host for luminescent lanthanide complexes is poly-(methyl methacrylate) (PMMA), which is transparent at wavelengths longer than 250 nm.…”

“…There has been growing interest in the design and synthesis of lanthanide-based coordination polymers motivated by their fascinating structure and the exploitable applications in luminescent materials, molecular adsorption, bimetallic catalysis and so on [1][2][3][4][5][6].T he polycarboxylic ligands have been proved to be extremelyversatile organicligands due to thefactthattheycan exhibit flexible coordination modes, including chelating, bidentate bridging or chelating bridging modes [7,8]. As an extension of research toward rational design and preparation of lanthanide coordination polymer, we recently have isolated anovel three-dimensional terbium (III) coordinated polymer containing two types of ligands (pyridine-2,5-dicarboxylate and picolinate) [Tb(C 7 H 3 NO 4 )(C 6 H 4 NO 2 )(H 2 O)] n under ionothermal conditions using the ionicliquid1-ethyl-3-methylimidazolium([Emim]Br) as solvent.Asillustrated in theFigure,the asymmetricunit of title compound contains one Tb(III) cation, one pyridine-2,5-dicarboxylate anion, one picolinate anion and one coordinated water molecule.…”
