Coordination complexes with aggregation-induced-emission (AIE) behavior has drawn much attention because of their promising applications. Conventionally, the AIE-active metal-organic complexes are prepared from an AIE-active organic ligand, and the construction of such coordination complexes from aggregation-caused-quenching (ACQ) ligands is still challenging. Herein, we have synthesized two new cyclic trinuclear complexes (CTCs), namely, 1 and 2, from copper(I) and silver(I) and a ACQ ligand [4-(3,5-dimethyl-1H-pyrazol-4-yl)benzaldehyde, HL]. (1) Exhibited AIE behavior, and the emission intensity is enhanced ~20 times when it aggregates, which can be attributed to its tight packing and multiple intermol. hydrogen bonds that restrained the intramol. rotation, as confirmed by single-crystal X-ray diffraction anal. On the other hand, (2) displayed ACQ effects, and the emission intensity is decreased ~5 times when it aggregates. This ACQ behavior of 2 is related to its loose packing and free rotation of the ligand in crystals, resulting in nonradiative decay and fluorescence quenching. Interestingly, the CTCs 1 and 2 both exhibited a good affinity to gold(III) ions, allowing selective detection and sensing of gold ions. More importantly, the 2 shows a good limit of detection (3.28μmol/L) and an ultrafast responsive time (~2 s). Our studies pave a new route to designing novel AIE-active coordination complexes and further exploring the functionality of CTCs. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Application of 76-83-5).
(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Application of 76-83-5
