White‐light emitting materials have become a hot research field of luminescent MOF (Metal–Organic Framework) because of its high practical application value. Herein, we successfully synthesized and characterized a rht‐type fluorescent MOF Zn‐TDPAT [H6TDPAT = 2,4,6‐tris(3,5‐dicarboxylphenylamino)‐1,3,5‐triazine] with a topology of (3, 24) connected nodes. A series of MOFs materials x%Tb + y%Eu@Zn‐TDPAT were prepared by incorporating different concentrations of green emission center Tb3+ and red emission center Eu3+ into the blue‐emitting Zn‐MOF. The luminescence properties of MOFs materials x%Tb + y%Eu@Zn‐TDPAT can be effectively adjusted by incorporating different concentrations of Tb3+ and Eu3+ and can obtain multi‐color luminescence properties from blue, blue‐green, green, yellow green, yellow, blue‐red, yellow‐red and white. According to trichromatic mechanism, by reasonably matching the intensity of blue light, green light and red light emitted by x%Tb + y%Eu@Zn‐TDPAT at 420, 543 and 616 nm, MOFs materials 0.75%Tb + 5%Eu@Zn‐TDPAT, 0.65%Tb + 5.5%Eu@Zn‐TDPAT and 0.5%Tb + 7.5%Eu@Zn‐TDPAT with white‐light emission are obtained. Their CIE coordinates are 0.3162, 0.3345 (0.3162, 0.3345), (0.3138, 0.3339) and (0.3329, 0.3222), respectively, which are very close to ideal white‐light emission (0.3333,0.3333).

“…32−34 On the other hand, N-donor ligands with conjugated π electrons are inherently luminescent because of the π−π* and n−π* transitions. 4,35 Consequently, heteroleptic systems combining a N-donor ligand and polycarboxylate may allow for the assembly of lanthanide CPs with improved structural modularity, variable dimensionality, and enhanced PL tunability.…”

“…The rational design and synthesis of lanthanide (Ln) coordination polymers (CPs) with a wide range of structural diversities have captured continuous research attention because they offer potential applications in a myriad of fields including catalysis, separation, luminescence sensing, magnetism, etc. − Considerable diversity of topologies, ranging from one-dimensional (1D) chains to two-dimensional (2D) lamellar networks to three-dimensional (3D) open frameworks, has been documented for CPs, while delicate tailoring of the network dimensionality and fine-tuning of the properties of CPs remain challenging. − The construction of CPs can be influenced by several factors, including the synthetic conditions, ionic radius, and electronic configuration of the metal center, the presence of a counterion, and the coordination mode of the ligand. − For example, dimensional reduction from 3D to 2D networks of lanthanide oxalates was realized by incorporating Ln ions with reducing sizes . Uranium–organic frameworks (UOFs) with various dimensionalities (1D to 3D) and ion-exchange capacities were constructed by templating with different tetraalkylammonium countercations .…”

Targeted synthesis, through a heteroleptic methodology, has resulted in three types of lanthanide (Ln) coordination polymers (CPs) with tailored dimensionality, tunable photoluminescent colors, and distinct luminescence quenching upon UV and X-ray irradiation. The homoleptic Ln(tpbz)(NO 3 ) 2 [CP-1; tpbz = 4-(2,2′:6′,2″-terpyridin-4′-yl)benzoate] is assembled from Ln cations and bridging tpbz ligands, accompanied by the decoration of NO 3 − anions, forming a one-dimensional (1D) chain structure. The presence of ancillary dicarboxylate linkers, 1,4-benzenedicarboxylate (bdc) and 2,5-thiophenedicarboxylate (tdc), promotes additional bridging between 1D chains to form a two-dimensional layer and a three-dimensional framework for Ln(tpbz)(bdc) (CP-2) and Ln(tpbz)(tdc) (CP-3), respectively. The multicolor and luminescence properties of the obtained CPs were investigated, displaying typical red Eu III -based and green Tb III -based emissions. The Sm III -bearing CP-1−CP-3, however, exhibit diverse ratiometric Ln IIIand ligand-based emissions, with the photoluminescent colors varying from pink to orange to cyan. Notably, the Tb III -containing CP-1−CP-3 display distinct luminescence quenching upon continuous exposure to UV and X-ray irradiation. To our best knowledge, CP-2-Tb represents one of the most sensitive UV dosage probes (3.2 × 10 −7 J) among all CPs.

“…Molecular photonics is a modern branch of science and its active areas of study are development and fabrication of highly functional luminescent materials and devices [1][2][3][4][5][6][7]. Among many different types of luminescent compounds (e.g., organic compounds, quantum dots, metal-ligand complex), lanthanide (III) coordination compounds are very promising candidates for development of luminescent molecular photonics materials and devices due to their unique photophysical properties, such as a narrow-band luminescence with a high quantum yield and a long lifetime [8].…”

Photostable Anisometric Lanthanide Complexes as Promising Materials for Optical Applications

Uniform luminescent films with high optical quality are promising materials for modern molecular photonics. Such film materials based on β-diketonate complexes of lanthanides have the following application problem: rapid luminescence degradation under UV radiation, low thermostability, poor mechanical properties, and aggregation propensity. An alternative approach to solving these problems is the use of anisometric analogues of β-diketonate compounds of lanthanides (III). The main advantage of such compounds is that they do not crystallize because of long hydrocarbon substituents in the structure of complexes, so they can be used to fabricate thin nano-, micro-, and macroscale uniform film materials by a melt-processing technique at relatively low temperatures, as well as by spin-coating. The method of fabrication of microscale luminescent film materials with controlled optical properties from anisometric analogues of Ln(DBM) 3 Phen and Ln(bzac) 3 Phen complexes (Ln = Eu, Tb) is proposed in this paper. Within the framework of this research, we developed original films which are highly uniform and transparent. An important advantage of these films is their high photostability and potential for applications as reusable luminescent sensors and light converters.Photonics 2019, 6, 110 2 of 10 application problem: rapid luminescence degradation under UV radiation, low thermostability, poor mechanical properties and propensity to aggregation [9,10]. A possible solution is incorporating these compounds into host matrices (e.g., organic polymers, ionic liquids, zeolites, and etc.) [11][12][13]. There are also other methods of fabricating film materials based on these compounds, such as electro deposition and sol-gel technology [1][2][3].Another problem of many film materials based on β-diketonate complexes of lanthanides is that their adsorption band is limited by the UV range. Therefore, UV sources are required to excite luminescence in such films, such sources are unsuitable in many applications for certain reasons (such as low brightness and high cost of such devices as compared to visible light sources). Thus, an urgent problem of molecular photonics is to broaden this adsorption band so it can include the visible light range.The solutions for this problem offered today are known to be based on the following approaches: synthetic modification of β-diketonate ligands and coordination of complex chromophores to tris(β-diketonates) of lanthanides(III) with capabilities of efficient visible light adsorption. For example, it is challenging to select a proper solvent for both a matrix and a complex, where, in addition, this complex must not dissociate.An alternative approach to solution of these problems is the use of anisometric analogues of β-diketonate compounds of lanthanides (III) [14,15]. The main advantage of such compounds is that they do not crystallize because of long hydrocarbon substituents in the structure of complexes and possess thermostable properties [16], so they can be used to fabricate thin nano-, micro-...
