Crystal-engineering and luminescence studies of 1,3,5-tris(3-pyridylethynyl)benzene or 1,3,5-tris(4-pyridylethynyl)benzene with copper(i) iodides

Abstract

The interlocking of 1-D frameworks into the 28-membered rings of the adjacent chains generates a novel 1-D (1-D → 1-D) polyrotaxane framework of 3.

A 1D Cu(i)–I-pyrazine coordination polymer with controlled pressure-induced phase transition and opto-electronic response depending on mechanical stimuli, temperature, and CuI content

“…4 and Table S3, ESI †). 52 Additionally, [CuI(PyzBr)] n displays supramolecular hydrogen bond type interactions between one of the free N of the pyrazine ligand and the H of the neighbouring ligand forming the next chain (NÁ Á ÁH = 2.670 Å) as observed in Fig. 3a.…”

“…4 and Table S3, ESI †). 4,52,54 Therefore, there is evidence that the PL intensity is governed by the CuÁ Á ÁCu distances. Its PL spectral positions can be explained by the different 3 CC and [(I + Cu)LCT] contributions to emission.…”

A Zn(II) Metallocycle as Platform to Assemble a 1D + 1D → 1D Polyrotaxane via π···π Stacking of an Ancillary Ligand

“…This interpenetrated topology is very rare. Indeed, six examples of 1D + 1D → 1D polyrotaxane-based on metallocycle rings have been reported so far [9,[26][27][28][29][30][31]. However, only for the coordination-driven [Cu 2 L 2 (bipy)] n discussed above [9] and the π•••π stacking-supported polyrotaxane here presented, the extended network is based on a metallocycle [M 2 L 2 ] (M = Cu 2+ and Zn 2+ ) that exists in solution as a discrete unit and that can act as a platform for the reversible self-assembly of the intertwined structure [9].…”

State of the art methods and challenges of luminescent metal–organic frameworks for antibiotic detection

“…The Cu(I) cation can coordi-nate with the I-donor to generate various copper iodide clusters with nontoxic, low-cost, and photoactive properties, resulting in their potential applications in photophysics and photochemistry, such as light-emitting devices and responsive luminescent solid-state materials. 81,82 Meanwhile, copper iodide clusters are easily assembled with pyridine ligands or S-donor ligands to construct plentiful networks and various luminescence emissions. 83 Recently, two Cu x I y -based LMOFs have been reported as luminescence sensors for monitoring antibiotics.…”
