Selective sensing of CrVI and FeIII ions in aqueous solution by an exceptionally stable TbIII-organic framework with an AIE-active ligand

We herein report a new lanthanide metal-organic framework (MOF) that exhibits excellent chemical stability, especially in the aqueous solution over a wide pH range from 1 to 14. In contrast to many reported lanthanide MOFs, this Tb-based MOF emits cyan fluorescence inherited from the integrated AIE-active ligand, rather than Ln3+ ions. More remarkably, its fluorescence signal features a highly selective and sensitive “turn-off” response toward CrO42?, Cr2O72? and Fe3+ ions, highlighted with the low detection limits down to 68.18, 69.85 and 138.8 ppm, respectively. Thus, the exceptional structural stability and sensing performance render this material able to be a superior luminescent sensor for heavy metal ions in wastewater.

Rational design of a high-efficiency, multivariate metal-organic framework phosphor for white led bulbs

Developing rare-earth element (REE) free yellow phosphors that can be excited by 455 nm blue light will help to decrease the environmental impact of manufacturing energy efficient white light-emitting diodes (WLEDs), decrease their cost of production, and accelerate their adoption across the globe. Luminescent metal-organic frameworks (LMOFs) demonstrate strong potential for use as phosphor materials and have been investigated intensively in recent years. However, the majority are not suitable for the current WLED technology due to their lack of blue excitability. Therefore, designing highly efficient blue-excitable, yellow-emitting, REE free LMOFs is much needed. With an internal quantum yield of 76% at 455 nm excitation, LMOF-231 is the most efficient blue-excitable yellow-emitting LMOF phosphor reported to date. Spectroscopic studies suggest that this quantum yield could be further improved by narrowing the material's bandgap. Based on this information and guided by DFT calculations, we apply a ligand substitution strategy to produce a semi-fluorinated analogue of LMOF-231, LMOF-305. With an internal quantum yield of 88% (λem = 550 nm) under 455 nm excitation, this LMOF sets a new record for luminescent efficiency in yellow-emitting, blue-excitable, REE free LMOF phosphors. Temperature-dependent and polarized photoluminescence (PL) studies have provided insight on the mechanism of emission and origin of the significant PL enhancement.

The self-assembly and chiroptical properties of tetraphenylethylene dicycle tetracholesterol with an AIE effect

The immobilized propeller-like conformation of tetraphenylethylene (TPE) can be used to emit strong circularly polarized luminescence (CPL) light, but the immobilized propeller-like conformation must be resolved. A single-handed helical conformation of TPE units induced by chiral group(s) that do not need resolution can also enable CPL emission, but related research is very rare. In this paper, TPE dicycle tetracholesterol is synthesized which could self-assemble into nano-tubes with a double molecule-layer shell, and which showed a fluorescence quantum yield of >76%. One film composed of nano-tubes displayed an enhanced first positive circular dichroism (CD) effect and emitted strong positive CPL light. A suspension or solution of the TPE dicycle tetracholesterol in DCE had a first negative CD band and negative CPL emission. In contrast, TPE tetracholesterol without intramolecular cyclization self-assembled into very soft "noodle-like" aggregations and showed very weak CD signals and CPL emission. The TPE dicycle tetracholesterol had a large CPL dissymmetric factor (≤3.0 × 10-3), which was 30 times larger than the TPE tetracholesterol without cycles. Due to the strong bisignate band in the CD spectrum of TPE dicycle tetracholesterol and the absence of a helical structure in aggregates, the CD and CPL signals of the TPE dicycle tetracholesterol could be ascribed to the prevailing single-handed propeller-like conformation of TPE units induced by chiral cholesterol groups.

A Biomimetic Supramolecular Approach for Charge Transfer between Donor and Acceptor Chromophores with Aggregation-Induced Emission

Supramolecular assembly of chromophores with inherent resistance to aggregation-induced self-quenching is significant to applications such as chemical sensing and organic light emitting diodes (OLEDs). In this work, molecular gels with aggregation-induced emission (AIE) are constructed by simply coassembling AIE chromophores (electron donor or acceptor) with a nonfluorescent molecular gelator. The binary gels are fluorescent even at very low concentrations of the AIE chromophores, indicating that the rotation of their aromatic cores is restricted in the gel network. In tertiary gels, the fluorescence of the donor chromophore can be efficiently reduced by the acceptor chromophore through a combination of static and dynamic quenching process, via charge transfer from the donor to the acceptor. This work demonstrates a convenient approach to fabricate a supramolecular charge transfer system using an AIE donor and acceptor.

Pore Environment Control and Enhanced Performance of Enzymes Infiltrated in Covalent Organic Frameworks

In the drive toward green and sustainable methodologies for chemicals manufacturing, biocatalysts are predicted to have much to offer in the years to come. That being said, their practical applications are often hampered by a lack of long-term operational stability, limited operating range, and a low recyclability for the enzymes utilized. Herein, we show how covalent organic frameworks (COFs) possess all the necessary requirements needed to serve as ideal host materials for enzymes. The resultant biocomposites of this study have shown the ability boost the stability and robustness of the enzyme in question, namely lipase PS, while also displaying activities far outperforming the free enzyme and biocomposites made from other types of porous materials, such as mesoporous silica and metal-organic frameworks, exemplified in the kinetic resolution of the alcohol assays performed. The ability to easily tune the pore environment of a COF using monomers bearing specific functional groups can improve its compatibility with a given enzyme. As a result, the orientation of the enzyme active site can be modulated through designed interactions between both components, thus improving the enzymatic activity of the biocomposites. Moreover, in comparison with their amorphous analogues, the well-defined COF pore channels not only make the accommodated enzymes more accessible to the reagents but also serve as stronger shields to safeguard the enzymes from deactivation, as evidenced by superior activities and tolerance to harsh environments. The amenability of COFs, along with our increasing understanding of the design rules for stabilizing enzymes in an accessible fashion, gives great promise for providing "off the shelf" biocatalysts for synthetic transformations.

Two-Dimensional Metal-Organic Layers as a Bright and Processable Phosphor for Fast White-Light Communication

A metal–organic layer (MOL) is a new type of 2D material that is derived from metal–organic frameworks (MOFs) by reducing one dimension to a single layer or a few layers. Tetraphenylethylene-based tetracarboxylate ligands (TCBPE), with aggregation-induced emission properties, were assembled into the first luminescent MOL by linking with Zr6O4(OH)6(H2O)2(HCO2)6 clusters. The emissive MOL can replace the lanthanide phosphors in white light emitting diodes (WLEDs) with remarkable processability, color rendering, and brightness. Importantly, the MOL-WLED exhibited a physical switching speed three times that of commercial WLEDs, which is crucial for visible-light communication (VLC), an alternative wireless communication technology to Wi-Fi and Bluetooth, by using room lighting to carry transmitted signals. The short fluorescence lifetime (2.6 ns) together with high quantum yield (50 %) of the MOL affords fast switching of the assembled WLEDs for efficient information encoding and transmission.

Piezofluorochromic metal-organic framework: A microscissor lift

We have successfully constructed a metal-organic framework, denoted as PCN-128W, starting from chromophoric linker and zirconium salt. PCN-128W exhibits interesting piezofluorochromic behavior, the color reversibly changes from white to yellow and so does the emission maximum from 470 to 538 nm. The stepwise fluorescence change was monitored by fluorospectroscopy which demonstrated gradual shift of the emission maximum when sequential compression was exerted. In order to gain deep insights into the piezofluorochromic mechanism, both the white and yellow phases are structurally characterized.
