“…In Figure , the microphotoluminescent (micro-PL) images depicted the blue and green emission in single crystal of [Zn(μ-6-ani) 2 ].

Among the recent developments in metal-organic frameworks (MOFs), porous layered coordination polymers (CPs) have garnered attention due to their modular nature and tunable structures. These factors enable a number of properties and applications, including gas and guest sorption, storage and separation of gases and small molecules, catalysis, luminescence, sensing, magnetism, and energy storage and conversion. Among MOFs, two-dimensional (2D) compounds are also known as 2D CPs or 2D MOFs. Since the discovery of graphene in 2004, 2D materials have also been widely studied. Several 2D MOFs are suitable for exfoliation as ultrathin nanosheets similar to graphene and other 2D materials, making these layered structures useful and unique for various technological applications. Furthermore, these layered structures have fascinating topological networks and entanglements. This review provides an overview of different aspects of 2D MOF layered architectures such as topology, interpenetration, structural transformations, properties, and applications.

“…A systematic study of some factors, namely pH and solvents, led to [Zn 2 (ia) 2 (H 2 O) 4 ] n ( 4 ) and {[Zn 2 (ia) 2 (DMF)] n ·H 2 O} n ( 5 ) (H 2 ia = itaconic acid). Interestingly, both compounds exhibit blue fluorescence and green phosphorescence that entails less frequent long-lasting phosphorescence [ 26 ].…”

This review considers the applications of Zn(II) carboxylate-based coordination polymers (Zn-CBCPs), such as sensors, catalysts, species with potential in infections and cancers treatment, as well as storage and drug-carrier materials. The nature of organic luminophores, especially both the rigid carboxylate and the ancillary N-donor bridging ligand, together with the alignment in Zn-CBCPs and their intermolecular interaction modulate the luminescence properties and allow the sensing of a variety of inorganic and organic pollutants. The ability of Zn(II) to act as a good Lewis acid allowed the involvement of Zn-CBCPs either in dye elimination from wastewater through photocatalysis or in pathogenic microorganism or tumor inhibition. In addition, the pores developed inside of the network provided the possibility for some species to store gaseous or liquid molecules, as well as to deliver some drugs for improved treatment.

“…So far, although many coordination polymers with RTP behaviors have been reported, almost all of them are based on aromatic ligands. − There is only one report of coordination polymers based on nonaromatic ligands with phosphorescent behaviors, but their phosphorescence can only be observed at very low temperatures (∼ 10 K) . Compared with the nonaromatic ligands (itaconic acid) reported in the literature, acetate has a smaller substituent to bind the carboxyl group, which is more conducive to the production of compounds with a high carboxyl group density. Therefore, compound 1 shows RTP properties.…”

“…Furthermore, metal ions can also effectively promote spin–orbit coupling through the heavy atom effect. , To date, some coordination polymers with RTP behavior have been reported. ,− , However, so far all of the reported RTP coordination polymers are based on aromatic (conventional) ligands. As we know, there is only one report on coordination polymers with long lifetime phosphorescence based on nonaromatic ligands, but the compounds show the property only at an extremely low temperature (10 K) . Considering the advantages of coordination polymer-type RTP materials, it is necessary to develop such materials based on nonaromatic (nonconventional) ligands.…”

Color-Tunable Long-Lived Room-Temperature Phosphorescence in a Coordination Polymer Based on a Nonaromatic Ligand and Its Phosphor/Coordination Polymer-Doped Systems

Long-lived room-temperature phosphorescence (RTP) from coordination polymers has attracted considerable attention owing to their intensive applications in diverse fields. However, the reported compounds are all based on aromatic ligands. Here, we report a two-dimensional RTP coordination polymer (1) based on a nonconventional nonaromatic ligand. It is facilely synthesized by recrystallizing calcium acetate in dimethyl sulfoxide (DMSO) solvent and has a blue-green RTP with a lifetime of 534.64 ms. The density of carboxyl groups is considered to be an important factor in affecting the RTP properties of such coordination polymers based on nonaromatic carboxyl ligands. In addition, the RTP emission of such nonconventional RTP materials is proved to be tunable by trace doping of organic phosphors. Blue, green, yellow, and orange RTP emissions with durations of 3–7 s can be obtained by doping different phosphors into 1. Finally, lifetime-encoding application is successfully performed using the doped systems. The work not only greatly expands the range of ligands that can be used to construct RTP coordination polymers but also achieves a wide range of adjustments to the RTP emission color of nonconventional RTP materials.
