Reaction of a semi-rigid tripodal ligand 1,1',1''-(2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene)tripyridinium-4-olate) (TTP) with Ln(3+) (Ln = Eu, Gd) afforded rare (3,12)-connected metal-organic frameworks (MOFs). A topological simplification of such highly connected 3D MOFs on the basis of 2D CdI(2) (3,6)-nets is proposed. The luminescent and anion exchange properties of the compounds we...

A hydrogen polysulfide mediated aziridine ring-opening reaction was discovered. Based on this reaction, a novel H2S(n)-specific chemosensor (AP) was developed. AP showed high sensitivity and selectivity for H2S(n). Notably, the fluorescent turn-on product (1) exhibited excellent two-photon photophysical properties, a large Stokes shift, and high solid state luminescent efficiency.

A general, efficient method is demonstrated for exchanging native oxyanionic ligands on inorganic nanocrystals with functional trimethylsilylated (TMS) chalcogenido ligands. In addition, newly synthesized TMS mixed chalcogenides leverage preferential reactivity of TMS-S bonds over TMS-O bonds, enabling efficient transfer of luminescent nanocrystals into aqueous media with retention of their opt...

Luminescent liquid crystals have received significant research interest due to their wide range of applications. Here, new pyridine derivatives were designed as liquid crystalline materials. They were successfully synthesized via appropriate synthetic routes, their structures confirmed by various spectral techniques, and finally characterized for their mesogenic, optical and optoelectronic prop...

We have synthesised a neutral, water-soluble, Pt(II) complex able to aggregate more efficiently in aqueous solutions than in organic solvents. The aggregates are luminescent and are not quenched by molecular oxygen. Further, we have prepared phosphorescent hydrogels utilising host-guest interactions between cyclodextrins and the tetraethylene glycol tails of the Pt(II) complex. The soft assembl...

For the first time, mechanochemical synthesis has been used for the preparation of crystalline and amorphous dinuclear gold(i) helicates, [Au2L2](X)2 (L = xantphos; X = CF3SO3, SCN, BF4 and PF6), that show anion- and phase-switchable luminescence properties. This solid-state approach provides strategies for developing switchable luminescent materials.

Some ruthenium (II) polypyridyl complexes with a bis-chalcone (obtained by the condensation of 3-methyl-thiophene-2-carboxaldehyde and 4-acetyl pyridine) have been synthesized and characterized spectroscopically (IR, NMR, UV/Vis), conductimetric, elemental analysis and FAB mass data. Their luminescent, redox and Li(+) binding properties have been studied. The anti-HIV and antitumour activities ...

Luminescent acentric and homochiral coordination compounds, which possess new topological networks, multiple helical structures and NLO properties, have been generated through the control of a versatile asymmetric ligand as well as inorganic anions, and this suggests a new protocol for preparing acentric and chiral materials.

We combined classical atomistic simulation and crystal field models to describe the origin of defects their influence on luminescent properties Eu-doped NaMgF3 in orthorhombic phase.

Tunable luminescent materials that respond to different external stimuli have attracted great attention during the last few years, owing to their potential applications in fluorescent switches, sensors, and optical recording devices. Mechanisms responsible for the change in luminescence include chemical reactions and alteration of the molecular packing mode. Since solid-state chemical reactions...
