“…The response values (ΔR/R 0 ) of NO 2 sensors reported in recent literatures are illustrated in Figure 4f, and the detailed sensing properties are summarized in Table S2 in the Supporting Information. [49][50][51][52][53][54][55][56] Although the response of Pd@Cu 3 (HHTP) 2 was slightly lower than those of other materials, a significant improvement in MOF-based sensors has been achieved in this work by combining the metal NPs with C-MOFs. The Pd@ Cu 3 (HHTP) 2 exhibited the highest NO 2 response among MOFbased sensors reported to date, including MOFs, C-MOFs, and MOF derivatives.…”

Conductive porous materials having a high surface reactivity offer great promise for a broad range of applications. However, a general and scalable synthesis of such materials remains challenging. In this work, the facile synthesis of catalytic metal nanoparticles (NPs) embedded in 2D metal–organic frameworks (MOFs) is reported as highly active and conductive porous materials. After the assembly of 2D conductive MOFs (C‐MOFs), i.e., Cu3(hexahydroxytriphenylene)2 [Cu3(HHTP)2], Pd or Pt NPs are functionalized within the cavities of C‐MOFs by infiltration of metal ions and subsequent reduction. The unique structure of Cu3(HHTP)2 with a cavity size of 2 nm confines the bulk growth of metal NPs, resulting in ultra‐small (≈2 nm) and well‐dispersed metal NPs loaded in 2D C‐MOFs. The Pd or Pt NPs‐loaded Cu3(HHTP)2 exhibits remarkably improved NO2 sensing performance at room temperature due to the high reactivity of catalytic metal NPs and the high porosity of C‐MOFs. The catalytic effect of Pd and Pt NPs on NO2 sensing of Cu3(HHTP)2, in terms of reaction rate kinetics and activation energy, is demonstrated.

“…Meanwhile, we also studied the effect of H 2 S concentration for the fluorescent test paper. As shown in Figure S19 (Supporting Information), the lightened degree of the fluorescent test paper increases with the concentration increase of H 2 S gas, and the LOD is lower than 30 ppb, which was lower than many other reported sensors for detecting H 2 S. [49,50] All the results suggested that the Zr(TBAPy) 5 (TCPP)-based fluorescent test paper can high selectively and sensitively detect H 2 S gas in real-time.…”

The development of fluorescence turn-on probes for selectively sensing toxic gases and visualization identification of fingerprints is significantly important for society security and human health. Here, Zr is used as the metal center and 1,3,6,8-tetra (4-carboxylphenyl) pyrene (TBAPy) and tetrakis(4-carboxyphenyl)porphyrin (TCPP) as double linkers to synthesize a novel Zr(TBAPy) (TCPP) material. Results indicate that Zr(TBAPy) (TCPP) can be used as a fluorescence turn-on probe for highly selective and sensitive detection of H S gas and its derivatives S in aqueous solutions with an extremely low concentration (≈1 ppb) and fast response time (<10 s). Moreover, by tailoring the particle size of samples, it is found that Zr(TBAPy) (TCPP) can efficiently achieve the visualization identification of fingerprints due to the fluorescence turn-on effect. All the results indicate that the Zr(TBAPy) (TCPP) is a promising multifunctional fluorescence turn-on probe.
