Fluorescence and phosphorescence of lutetium(III) and gadolinium(III) porphyrins for the intraratiometric oxygen sensing

Near‐IR Luminescent YbIII Coordination Polymers Composed of Pyrene Derivatives for Thermostable Oxygen Sensors

“…[7] Various other luminescent lanthanide(III) complexes with oxygen-sensing properties have also been reported. [8][9][10][11][12][13][14] Here, we focus on pyrene derivativesb earing carboxyl groups,T BAPy (1,3,6,8-tetrakis(p-benzoate)pyrene)a nd TIAPy (1,3,6,8-tetrakis(3,5-isophthalic acid)pyrene), for oxygen-sensitive lanthanide luminophores. These moieties are well known to be useful in the construction of three-dimensional metal coordination polymers, [15] ands uch polymers incorporating In III , Zr II ,C e III ,o rE u III have been found to have characteristicn anoporouss olid structuresa nd to show gasa dsorption.…”

Highly Efficient and Air‐Stable Lanthanide EuII Complex: New Emitter in Organic Light Emitting Diodes

“…The photoluminescence (PL) of lanthanide complexes is an interesting topic both from the perspective of basic research and application. [1] Based on the luminescence mechanisms, lanthanide complexes can be divided into mainly three types: f-f transition such as Tb III (4f 8 ) and Eu III (4f 6 ) complexes, [2] df transition such as Ce III (4f 1 ) and Eu II (4f 7 ) complexes, [3] and ligand-based transitions, such as La III (4f 0 ), Gd III (4f 7 ), and Lu III (4f 14 ) complexes, [4] among which the former two are characteristic central ion-based transitions. The investigation of luminescent lanthanide complex in organic light emitting diodes (OLEDs) can be traced back to 30 years ago, [5] when Kido et al first applied a Tb III complex as the emitter in OLEDs.…”

Lutetium-containing sinoporphyrin sodium: a water-soluble photosensitizer with balanced fluorescence and phosphorescence for ratiometric oxygen sensing

“…Remarkably, the F P of Lu-DVDMS in methanol is two orders of magnitude higher than those of previously reported Lu-porphyrins (e.g., Lu-tetrabenzoporphyrin). 23 Fig. 3(a) also shows the normalized luminescence spectrum of Gd-DVDMS recorded under the same experimental conditions.…”

“…Lutetium(III) is a lanthanide ion that can show the HAE and the 4f sub-shell of lutetium(III) is lled. Lutetium(III) has no 4f energy levels; thus, the energy transfer from the porphyrin ligand to lutetium(III) is also impossible, 23 similar to the case of Gd(III). Unlike Gd(III), Lu(III) is not paramagnetic because it has no uncoupled electrons.…”
