Thermally activated delayed fluorescence vs. room temperature phosphorescence by conformation control of organic single molecules

The time-resolved photophysical analysis of a multi-color-changing mechanochromic luminescent compound has been disclosed, which reveals distinct different emission paths to boost TADF and RTP of the emitter depending on its molecular conformations.

A simple photoluminescent strategy for pH and amine vapors detection based on Eu(iii)-complex functionalized material

A simple luminescence sensing strategy has been designed for pH and amine vapors detection after loaded luminescent compound Eu(DBM)3Phen (LMOF-1), Eu(DBM)3BPY (LMOF-2) on portable matrices such as neutral silica plate and normal filter paper.

A homochiral luminescent compound with four-fold symmetry as a potential chemosensor for nitroanilines

Crystal structure of the first homochiral luminescent compound of a dansylated amino acid (tyrosine) of Cu(ii), [Cu2(HTyr-N-Dan)4(H2O)2]·2H2O (1) (H2Tyr-N-Dan = N-dansyltyrosine), and selective sensing of nitroanilines by both the ligand and 1 are reported.

Synthesis, Characterization and Luminescence of Europium, Terbium Complexes of 1,1'-(Pyridin-2,6-Diyl) Bis-3-P-Tolylpropane-1,3-Dione

A new ligand, 1,1'-(pyridin-2,6-diyl)bis-3-p-tolylpropane-1,3-dione(H2L), was prepared and its crystal structure displays its enol isomer. The binary complex, Ln2L3·4H2O [Ln = Eu(III) and Tb(III)], were synthesized by the reaction of synthesized ligand (H2L) and Ln(III). With 1,10-phenanthroline (Phen) as the synergistic ligand, the ternary complex, Ln2L3(Phen)2 [Ln = Eu(III) and Tb(III)], were synthesized. The compounds were characterized by 1H-NMR spectroscopy, MS, IR, UV, DTA-TG and fluorescence spectrum. The luminescent properties of the ligand and its complexes were investigated and the results showed that the prepared ligand was a good luminescent compound, all complexes emitted characteristic luminescence of corresponding lanthanide ions and 1,10-phenanthroline as the synergistic ligand can obviously enhance the luminescence of Eu(III) in the ternary complex.
