“…The plot of the relative sensitivity against temperature in Figure e reveals maximum relative sensitivity of 16.14% K −1 at 359 K. Notably, a high S r of 9.01% K −1 at 353 K was also attained over the physiological temperature range (293–353 K), which outperforms existing luminescence thermometers in this temperature range (Table S2, Supporting Information) …”

applications. For example, mixed LnMOFs with a dual emission can be constructed by introducing two types of luminescent lanthanide ions into the frameworks. The temperature-sensitive intensity ratio of the dual emission provides self-referencing thermometry, which is immune to fluctuations in the excitation source and in the detection system. By controlling the concentration ratio of lanthanide components in the framework, the performance of the ratiometric thermometer can be readily adjusted. [1] LnMOF thermometers in previous reports were mainly prepared in the form of dispersed particles and intended for probing local temperatures. In order to enable mapping of temperature distribution over a large surface, efforts have been devoted to the synthesis of LnMOF films by depositing preformed LnMOF particles on various substrates. [2][3][4] For example, Cao and co-workers fabricated Ln@UiO-66 hybrid film on fluorinedoped tin oxide (FTO) glass by an electrophoretic deposition method, in which a CH 2 Cl 2 dispersion of MOF powders was placed in an electrode tank and treated under a DC voltage of 9 V for 5 min. [4] In an attempt to develop fast synthesis of LnMOF films, Bouwman and co-workers explored direct growth of mixed Gd/Tb MOF films on a Gd 2 O 3 substrate. The Gd 2 O 3 substrate was prepared by compressing Gd 2 O 3 powder at an ultrahigh temperature (1500 °C) to enhance the mechanical strength. The Gd 3+ ions act as nucleation sites for the growth of the MOF film by a hydrothermal synthesis method. [5] The preparation of Gd 2 O 3 substrate is complicated and the growth of film is at high pressure and temperature condition, which induces high cost in large-scale production. Thus, facile and scalable synthesis of large LnMOF films with a high thermal sensitivity remains an unfulfilled research.In this study, we report a one-step wet chemical synthesis for direct growth of mixed Tb/Eu-BTC MOF films on large quartz substrates (4 cm × 4 cm). Thermometric properties of the LnMOF films are investigated in the 298-383 K range. The thermal sensitivity of the LnMOF films as a function of lanthanide composition was investigated and correlated with the intramolecular energy transfer process. We also demonstrate real-time colorimetric thermal mapping using the Tb/Eu-BTC MOF film.LnMOF composed of 1,3,5-benzenetricarboxylate (H 3 BTC) and lanthanide ions was first reported by Yaghi and co-workers [6] Mixed lanthanide metal-organic framework (LnMOF) films are directly grown on a quartz substrate through a wet chemical synthesis. Thermometric properties of the LnMOF films originating from temperature dependent emission intensity ratio of Tb/Eu are systematically investigated in the 298-383 K range. At an optimized Tb/Eu concentration ratio of 98.0:2.0, the ratiometric thermometer registers a high relative sensitivity of 16.14% K −1 at 359 K. As the temperature increases from 298 to 383 K, the LnMOF film thermometer also displays a distinct change in emission color from green to red, corresponding to a shift in Commission Inte...

“…Another most widely used approach to synthesizing LP@ MOFs is the one-pot method, in which the as-synthesized LPs are encapsulated synchronically during the growth process of the MOF crystals. [165] Compared to the in situ growth that is usually suitable for the encapsulation of one type of LPs, the one-pot method can simultaneously encapsulate different LPs to achieve the multifunctionalization with the nonpropagating operation. For example, Huang and co-workers integrated a new fluorescence nanoprobe by simultaneously encapsulating CDs and curcumin (CCM) into the cavities of ZIF-8 MOF through one-pot route.…”

“…The encapsulation of luminescent guest species into the pores of the lanthanide MOFs can expand the emission ranges of ratiometric luminescent thermometers. [165] In 2015, Qian et al reported a ratiometric thermometer based on dye@MOF by incorporating a luminescent perylene dye into a porous lanthanide MOF [Eu 2 (QPTCA)(NO 3 ) 2 (DMF) 4 ]•(CH 3 CH 2 OH) 3 (ZJU-88, H 4 QPTCA = 1,1′:4′,1″:4″,1′″-quaterphenyl-3,3′″,5,5′″′″tetracarboxylic acid) (Figure 4a). [214] The obtained perylene@ ZJU-88 (0.1%) features both the characteristic emissions of Eu 3+ and perylene dyes.…”

“…[ 9–14 ] Therefore, the rational design and fabrication of different MOF structures are of great significance, as MOFs have been an emerging and fascinating subclass of crystalline porous inorganic‐organic hybrids. [ 15–18 ] In this context, MOFs and their derivatives have been well studied by many researchers in different applications, such as gas storage and separation, [ 19–21 ] gas removal, [ 22,23 ] pollutant removal, [ 24–27 ] heterogeneous catalysis, [ 28–30 ] drug delivery, [ 31–33 ] sensing, [ 34–37 ] and energy storage and conversion.

Multiporous metal‐organic frameworks (MOFs) have emerged as a subclass of highly crystalline inorganic‐organic materials, which are endowed with high surface areas, tunable pores, and fascinating nanostructures. Heterostructured MOF‐on‐MOF composites are recently becoming a research hotspot in the field of chemistry and materials science, which focus on the assembly of two or more different homogeneous or heterogeneous MOFs with various structures and morphologies. Compared with one single MOF, the dual MOF‐on‐MOF composites exhibit unprecedented tunability, hierarchical nanostructure, synergistic effect, and enhanced performance. Due to the difference of inorganic metals and organic ligands, the lattice parameters in a, b, and c directions in the single crystal cells could bring about subtle or large structural difference. It will result in the composite material with distinct growth methods to obtain secondary MOF grown from the initial MOF. In this review, the authors wish to mainly outline the latest synthetic strategies of heterostructured MOF‐on‐MOFs and their derivatives, including ordered epitaxial growth, random epitaxial growth, etc., which show the tutorial guidelines for the further development of various MOF‐on‐MOFs.
