Assembling metal‐organic frameworks (MOFs) into high‐performance macroscopic membranes is crucial but still challenging. MOF‐containing hybrid membranes can effectively integrate the advantages of flexible guest materials and MOFs. Nevertheless, the inherent limitations in fully harnessing the distinct characteristics of MOFs persist due to the substantial guest material content necessitated in membrane...
Photocatalytic membranes can effectively integrate membrane separation and photocatalytic degradation processes to provide an eco‐friendly solution for efficient water purification. It is of great significance to develop highly efficient photocatalytic membranes driven by visible light to ensure the long‐term stability of membrane separation systems and the maximum utilization of solar energy. Metal‐organic...
Alzheimer's disease (AD) is a severe neurodegenerative condition characterized by inflammation, beta‐amyloid (Aβ) plaques, and neurodegeneration, which currently lack effective treatments. Chiral nanomaterials have emerged as a promising option for treating neurodegenerative disorders due to their high biocompatibility, strong sustained release ability, and specific enantiomer selectivity. The development...
1D van der Waals (vdW) materials have attracted significant interest in recent years due to their giant anisotropic and weak interlayer‐coupled characters. More 1D vdW materials are urgently to be exploited for satisfying the practice requirement. Herein, the study of 1D vdW ternary HfSnS3 high‐quality single crystals grown via the chemical vapor transport technique is reported. The Raman vibration...
Because of their exceptional physical and thermal properties, cellulose nanocrystals (CNCs) are a highly promising bio‐based material for reinforcing fillers. Studies have revealed that some functional groups from CNCs can be used as a capping ligand to coordinate with metal nanoparticles or semiconductor quantum dots during the fabrication of novel complex materials. Therefore, through CNCs ligand...
For achieving high‐performance p‐i‐n perovskite solar cells (PSCs), hole transporting materials (HTMs) are critical to device functionality and represent a major bottleneck to further enhancing device stability and efficiency in the inverted devices. Three dopant‐free polymeric HTMs are developed based on different linkage sites of triphenylamine and phenylenevinylene repeating units in their main...
Adequately harvesting all excitons in a single molecule and inhibiting exciton losses caused by intermolecular interactions are two important factors for achieving high efficiencies thermally activated delayed fluorescence (TADF). One potential approach for optimizing these is to tune alignment of various excited state energy levels by using different doping concentrations. Unfortunately, emission...
Thermally activated delayed fluorescence (TADF) materials with extremely small singlet‐triplet energy offsets have opened new horizons for the development of metal‐free photosensitizers for photodynamic therapy (PDT) in recent years. However, the exploration of near‐infrared (NIR) TADF emitters for efficient two‐photon‐excited (TPE) PDT is still a formidable challenge, thus it has not been reported...
Photodynamic Therapy
In article number 2106215, Menglin Li, Jinfeng Zhang, and co‐workers develop a metal‐free photosensitizer (PS) based on thermally activated delayed fluorescence (TADF) nanoparticles, which demonstrates intrinsic two‐photon‐excited (TPE) property, near‐infrared emissive fluorescence, and singlet oxygen generation ability. Moreover, the TPE‐photodynamic therapy (PDT) performance...
Thiolate‐protected nanoclusters with different charge states usually show similar structure frameworks but different electronic configurations, which are proved to dramatically affect their properties such as magnetism, photoluminescence, and catalytic activity. Until now, few nanoclusters with alterable charge states have been reported and only some of them are structurally solved, limiting the in‐depth...
All‐inorganic semiconductor perovskite quantum dots (QDs) with outstanding optoelectronic properties have already been extensively investigated and implemented in various applications. However, great challenges exist for the fabrication of nanodevices including toxicity, fast anion‐exchange reactions, and unsatisfactory stability. Here, the ultrathin, core–shell structured SiO2 coated Mn2+ doped CsPbX...
In article number 1900484, Juan Du, Yu Chen, Yuxin Leng, and co‐workers fabricate ultrathin, core–shell structured CsPbMnX3@SiO2 (X=Cl, Br) quantum dots (QDs) by slowly hydrolyzing tetraethoxysilane at room temperature, showing high water and thermal stability, which reveals that these QDs are suitable as color‐conversion materials. White light‐emitting diodes fabricated with CsPbMnX3@SiO2 and CsPbBr...
Beam pen lithography (BPL) in the liquid phase is evaluated. The effect of tip‐substrate gap and aperture size on patterning performance is systematically investigated. As a proof‐of‐concept experiment, nanoarrays of nucleotides are synthesized using BPL in an organic medium, pointing toward the potential of using liquid phase BPL to perform localized photochemical reactions that require a liquid...
