“…15 It is highly possible to tailor desirable optoelectronic properties of such molecules by manipulation of the parent chromophore, which includes conjugation length control and the introduction of electron donating or withdrawing groups into the primary chemical structure. 16,17 In this work, to develop red phosphors with advantageous properties, a series of europium(III)-b-diketonate complexes based on diphenylethyne with different substituents were synthesized. Their photophysical properties, thermal stability, energy-transfer mechanism and structure-property relationships were investigated.…”

Six β-diketonate ligands were used to prepare the corresponding antenna europium(III) ternary complexes using 1,10-phenanthroline as an ancillary ligand. All the complexes exhibited high decomposition temperatures. Photophysical properties such as FT-IR spectra, UV-Vis absorption spectra, excitation and emission spectra, relative luminescent intensity ratios, luminescence decay curves and quantum yields based on the complexes were systematically studied and compared with each other. The energy-transfer mechanism was proposed as a ligand-sensitized luminescence process. Bright red light-emitting diodes (LEDs) were then fabricated by coating the complexes onto 395 nm-emitting InGaN chips. The light emission from the InGaN chips could be completely absorbed in the spectra of LEDs. The Commission International de I'Eclairage (CIE) chromaticity coordinates are close to the National Television Standard Committee (NTSC) standard value for the red color. All these findings indicate that these Eu(III) complexes are promising red phosphors for fabrication of near UV-based white LEDs.

“…This dual functionalities extend their potential applications to nonlinear optical materials, liquid crystal materials, and molecular devices [3] . Interestingly, it has been recently reported that this class of diynes also exhibits photoactivatable insecticidal properties and is a key structure for a potential class of highly efficient and low‐toxic ecological photoactivatable pesticides [4] . Diyne's pivotal role is evident in the synthesis of diverse alkynes types, the construction of macrocyclic alkynes, natural product synthesis and supramolecular fields [5] .…”

Glaser‐coupled synthesized 1,3‐diyne can participate in the generation of conjugated polymers and is now widely used in organic and polymer synthesis. Currently, the catalysts in coupling are mostly based on the complexation of noble metals with complex organic ligands, which inevitably increases the research cost and storage difficulty. However, polymetallic oxides (POMs), with acidic and redox properties, can be used as excellent inorganic ligands with low cost and easy storage. In this work, we have synthesized copper catalysts 1, (NH4)4[CuMo6O18(OH)6] with polymetallic oxides as inorganic ligands in a facile way and applied them in the coupling of alkynes to obtain (non)symmetrical conjugated 1,3‐diynes in high yields without bases, finally proposing a reasonable reaction path. In addition, the catalyst showed good tolerance to a variety of different groups, further demonstrating its excellent catalytic activity. It is worth mentioning that the catalyst maintained its good structure and activity after six cycles, demonstrating its promising potential for industrial applications. Thus, this paper provides a new strategy for the preparation of (un)symmetrical diynes using polymetallic oxides of Cu as catalysts, and also demonstrates the potential of multi‐acid catalysts for organocatalytic applications.
