“…As known, the rigidity of the polymer network is highly related to the temperature. , The temperature-dependent increase in polymer chain mobility reduces the rigidity of the polymer network, disrupting the polar–π interaction between PTF1 and the polymer matrices. Consequently, the emission at 540 nm originating from the CTC notably decreases, while the intrinsic emission of PTF1 at 455 nm increases, resulting in a pronounced fluorescence change with varying temperatures (Figure b).…”

Traditional fluorescent thermometers are often responsive to stimuli such as acid, moisture, solvents, light irradiation, and other stimuli, thereby limiting their practical applications. This is further intensified by the growing complexity of unconventional scenarios with various interfering stimuli. Here, we develop a versatile fluorescent thermometer featuring fluorophore PTF1 dispersed in a polymer matrix at a low loading. At room temperature, the rigidity of polymer network is high, rendering PTF1 a yellow fluorescence due to its antirigidochromic behavior. Increasing the temperature reduces the rigidity of PTF1, effectively restoring the intrinsic blue fluorescence of PTF1. Benefiting from the excellent encapsulation effect of polymer matrices, this thermometer exhibits an exceptional anti-interference ability. Further, it could be shaped into various forms, enabling temperature measurements in diverse scenarios. Moreover, it could be customized to irreversible working modes, rendering the temperature history with recording features. This work offers a design of a fluorescent thermometer with advanced features unattainable with conventional fluorophores.

“…Structural features endow MOF materials with immense feasibility in the construction of sensing platforms with the advantages of facilitating adsorbing and preconcentrating the analytes, targetoriented molecular recognition, and real-time self-reference detection. Herein, MOF-based sensory materials were classified by the signal response, such as luminescence enhancement/ quenching, [71][72][73] multi-emission/ratiometric fluorescence, [74][75][76] surface plasmon resonance (SPR), 77,78 surface-enhanced Raman scattering (SERS), 79 electrical impedance, 80,81 and cyclic voltammetry. [82][83][84] In the following sections, we will introduce these methods in the application fields of agricultural field operations, explosive detection, and point-of-care clinical analysis.…”

“…Metal–organic frameworks (MOFs) are porous crystalline compounds with periodic structures composed of metal ions/metal clusters and organic ligands. − They are widely used in catalysis, gas storage and separation, fluorescence sensing, electrical conductivity and energy storage, biology, and medicine − due to the advantages of a high specific surface area, uniform pore structures, and adjustable functional sites. Compared with other materials, the catalytic sites of MOFs are evenly distributed, which improves the selectivity and conversion of specific products. , So far, there have been many examples demonstrating the success of MOFs in catalyzing CO 2 cycloaddition.…”

Metal–organic frameworks (MOFs) have demonstrated potential for CO2 capture and conversion, which are of great importance to alleviate current global environmental problems. Considering that MOFs with large pores are not conducive to adsorption under atmospheric environments, it is critical to control MOF materials with suitable pore sizes and catalytic sites to facilitate CO2 adsorption and fixation. Based on this, cage space partition (CSP), a new strategy to precisely regulate the pore sizes of MOFs, is proposed herein. The feasibility of the CSP strategy is demonstrated in an extra-large metal–organic cage ([M60(BTC)24], M = Co or Ni, BTC = benzene-1,3,5-tricarboxylate), which connects adjacent small cages ([M12(BTC)12]) to form a parent skeleton. For the first CSP process, four typical pyridine-based triangular ligands (TPT, 2,4,6-tris(4-pyridyl)-1,3,5-triazine) are symmetrically inserted into the M60-cage via open metal sites, which transfer the parent skeleton into a novel CSP-MOF (SNNU-337). Furthermore, two larger tri-pyridine ligands (TPHAP, 2,5,8-tri(40-pyridyl)-1,3,4,6,7,9-hexaazaphenalene) are involved to fulfill the second CSP process through residue open metal sites distributed on the inner cage surface, which lead to another isostructural CSP-MOF material (SNNU-338). Oriented by the continuous π–π interactions, the trapped TPT and TPHAP partitioners are divided into two groups, which finally divided the whole large pore into seven small sections. Benefiting from the two-step CSP process, the low-pressure CO2 adsorption capacity of MOFs is remarkably enhanced. Grand canonical Monte Carlo simulations clearly indicate that the introduction of partition agents successfully regulates the internal aperture of the cage and thus enhances the interactions between the MOF skeleton and CO2 molecules. Moreover, the synergistic effects of CSP in large M60-cages and open metal sites in M12-cages make SNNU-337/338 MOFs excellent catalysts to catalyze CO2 cycloaddition with various epoxides.
