Summary: The study introduces a porphyrin-based two-dimensional layered metal-organic framework (MOF) (2DZnTcpp) for efficient sono-/photocatalytic degradation of organic dyes and bactericidal activity. The material features include avoiding pi-pi stacking, providing a porous space, increasing spin orbital coupling via the heavy atom effect, promoting singlet oxygen generation, and facilitating water splitting for hydroxyl radical generation.

Summary: Metal-organic backbone and thionyl chloride functionalized carbon nanotubes were successfully synthesized and introduced into carbon black to fabricate a novel electrochemical sensor for the simultaneous determination of hydroquinone, catechol, and resorcinol. The composite modified electrode showed excellent analytical performance with good linear relationships, low detection limits, and wide detection ranges. The sensor also demonstrated favorable reproducibility, stability, and selectivity for the target compounds, holding great potential for selective detection in environmental water samples.

Summary: We report the efficient separation of p-xylene (pX) from its xylene isomers using a microporous calcium-based metal-organic framework material (HIAM-203) with a flexible skeleton. The adsorption kinetics of o-xylene (oX) and m-xylene (mX) are slower than that of pX, and at an elevated temperature of 120°C, oX and mX are fully excluded while pX can be adsorbed. Experimental measurements and calculations support the capability of HIAM-203 for efficient separation of xylene isomers.

Summary: Metal-organic frameworks (MOFs) are promising alternatives for CO2RR due to their periodic arrangement of isolated metal active sites, but traditional MOFs have poor conductivity. Researchers have prepared conductive 2D phthalocyanine-based MOF nanosheets, which exhibit a high efficiency and selectivity for CO production.

Summary: In this study, two-dimensional (2D) metalloporphyrin-based MOF Zn-2[TCPP(M)] films with abundant pi-pi interactions were successfully fabricated by the liquid-phase epitaxial layer-by-layer approach and assembled into photodetectors. The ZnTCPP(M)-based photodetectors exhibited an excellent photoresponse, and the metalloporphyrinic groups in ZnTCPP(M) played a significant role in modulating the photoresponse. The ZnTCPP(Zn) film-based device showed the best photodetection performance with high on/off ratio, responsivity, short rise/fall times, and large detectivity.
