“…We recently reported a novel luminescent ionogel based on poly(ionic liquid). A new poly(ionic liquid) with terpyridine moieties incorporated in the polymer chain was prepared by polymerizing monomeric terpyridinefunctionalized ionic liquid [63]. One of the obvious advantages of the new poly (ionic liquid) over the previously reported ones is the availability of terpyridine groups in the repeating units of the polymer as shown in Fig.…”

“…The ionic liquids utilized in those studies play an important role in improving the photostability and thermal stability [23]. Furthermore, ionic liquids with special functional moieties like carboxyl groups [39] and terpyridine groups [40,63] can protect the RE 3+ ions from luminescence quenching caused by water molecules via coordinating the metal ions to oxygen atoms and nitrogen atoms, respectively. They can also act as the sensitizer for RE 3+ luminescence due to the energy transfer from ionic liquids to the metal ions.…”

Soft luminescent materials resulting from the introduction of rare earth compounds to ionic liquids favorably combine the properties of ionic liquids with unique optical properties of rare earth compounds such as sharp emission band, long decay time of the excited state, and the tunable emission color over the entire spectral range of interest from UV to infrared spectral region. This chapter summarizes the progress ever made in such kind of soft luminescent materials, especially those that have been made in our research group. Our emphasis is put on the preparation strategies for the soft luminescent materials, the luminescent ionogels prepared from the immobilization of rare earth-containing ionic liquids by organosilica and polymers, and the unexpected luminescent enhancement of Eu 3+ -β-diketonate complexes hosted in zeolite L nanocrystals and nanoclay upon addition of ionic liquid bearing bulky triethoxysilane groups in water.

“…The luminescence properties of the luminescent materialb ased on Te rpy-PIL, such as the quantum efficiency and decay time, are much higher than those of the correspondingl uminescent materialp repared from the monomer of Te rpy-PIL. [9] However,t he spatialp ositiono ft he terpyridine moieties was confined by the polymer scaffold;i nt his case, terpyridine cannot rotate freely, coordinate with the europium(III) ions, or protect the lanthanide efficiently.A dditionally, as ingle terpyridine ligand could not efficientlyr eplace water molecules in the first coordination sphere of europium(III). [10] Ta king the covalent incorporation of lanthanide-containing ILs into polymerm atricesa nd satisfying the coordination number of the central lanthanide ion into account,h erein, we report an ovel hybrid luminescent materialo btained upon complexation of ap olyethylene polymer derivativec ontaining benzoicacid moieties in each of the repeating units with al anthanide(III) (Ln = Eu and Tb) organic complex precursor, [Ln(hfa) 3 ]( HFA = hexafluoroacetylacetone).…”

A poly(ionic liquid) (BA-PIL) carrying a benzoic acid group in each repeating unit of the polymer architecture, which has the dual function of acting as a matrix and second ligand, has been developed. Through the incorporation of BA-PIL with the complex [Ln(hfa)3 ] (hfa=hexafluoroacetylacetone) as an emitting precursor, significant luminescence improvement was achieved in the obtained hybrid materials. Confinement of the lanthanide(III) complexes within the rigid chains of the polymer, together with replacement of the coordinated water molecules, are believed to be ascribed to the enhanced optical properties.

“…Remarkably, varying the amount of terpy incorporated into the polymer allows for the effective tuning of the selectivity of the resulting polymeric material towards ion sensing. Moreover, a terpy-functionalized poly(ionic liquid) has been utilized for coordination and selective recognition of europium ions that can be further employed in the preparation of novel luminescent materials [20,21].…”

Rational design of a material for rapid colorimetric Fe2+ detection

Wereport on the rational design of a novel TiO2 based screen-printed material suitable for sensitive and selective\ud detection of iron ions in water. This includes the synthesis and characterization of large mesoporous TiO2 nanostructures,\ud screen-printing of thick titania films on glass surfaces and their functionalization with 2,2′:6′,2″-\ud terpyridin-4′-ylphosphonic acid (terpy). The ultra-high affinity between iron ions and the TiO2-anchored terpy\ud receptor makes this system potentially applicable to the analysis of iron in environmental, food, biological, and\ud biomedical systems by a readily quantifiable colour change. Rapid (b30 s) colour change of the material from\ud white to magenta permits easy detection of as low as 0.3 ppm of Fe2+ by the naked eye. The intensity of the colour\ud change depends on the nature of the nanoparticles, the overall TiO2 film thickness, and the Fe2+ concentration.\ud The material was characterized using profilometry, diffuse reflectance UV–vis spectroscopy, and X-ray\ud photoelectron spectroscopy (XPS) before and after treatment with aqueous solutions of Fe2+. The designed material\ud shows colour reversibility upon treatment with EDTA solutions, which allows for multiple reuses of the\ud same film with no effect on sensitivity
