Abstract Porous metal–organic frameworks (MOFs) nanostructures constructed from metal ion/ion clusters and organic bridging ligands hold great promise for biomedicine applications. The developing of nanoagents achieving accurate diagnosis improved therapeutic effect is highly desirable. Herein, a new‐style versatile zirconium‐ferriporphyrin framework (Zr‐FeP MOF) nanoshuttles reported using facile one‐pot hydrothermal method. Zr‐FeP MOF enable simultaneously to generate abundant reactive...
All-perovskite tandem solar cells (TSCs) hold the promise of surpassing efficiency limits single-junction cells. However, enhancing TSC faces challenge significant open-circuit voltage (VOC) loss...
Abstract Hypoxic tumor microenvironment is the bottleneck of conventional photodynamic therapy (PDT) and significantly weakens overall therapeutic efficiency. Herein, versatile metal–organic framework (MOF) nanosheets (DBBC‐UiO) comprised bacteriochlorin ligand Hf 6 (µ 3 ‐O) 4 ‐OH) clusters to address this tricky issue are designed. The resulting DBBC‐UiO enables numerous superoxide anion radical (O 2 −• ) generation via a type I mechanism with 750 nm NIR‐laser irradiation, part which...
Abstract Herein, a cancer cell (MCF‐7 cell) membrane‐encapsulated dendritic mesoporous silica nanoparticle simultaneously functionalized with DNA‐photoacoustic (DNA‐PA) probes and glutathione (GSH)‐responsive DNA fuel strands for PA imaging of tumor‐related miRNA in living mice signal amplification ability is developed. It demonstrated that one target can trigger disassembly multiple fluorophore from the quencher aid GSH‐responsive via entropy‐driven process, resulting remarkable amplified...
Photodynamic therapy (PDT) possesses two pathways depending on the type of high-toxicity reactive oxygen species (ROS), superoxide anion radical (O2·–) and hydroxyl (·OH) generated through Type I singlet (1O2) II, inducing cancer cell apoptosis. However, low efficiency ROS generation poor biocompatibility are limitations traditional photosensitizers for PDT. Herein, inspired by photochemical reactions titanium dioxide porphyrin-based metal–organic frameworks, we developed a nanoplatform...
Abstract Significant advancements in perovskite solar cells (PSCs) have been driven by the engineering of interface between absorbers and charge transport layers. Inverted PSCs offer substantial potential with their high power conversion efficiency (PCE) enhanced compatibility for tandem cell applications. Conventional hole materials like poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) poly(triaryl amine) (PTAA) not only constrain PSC but also elevate fabrication costs. In...
Incorporating alkylammonium cations atop the 3D perovskite enables effective defect passivation and significantly enhances power conversion efficiency of solar cells. However, diversity durability this strategy have been limited to ligand type diffusion ligands due high reactivity. Here, we designed bulky "T-shaped" conjugated carbazole with inner π–π interaction enlarged steric hindrance minimize while maintaining effects. As verified by grazing incidence X-ray diffraction transient...
Perovskite-CIGS tandem solar cells offer unique benefits, such as high efficiencies and the possibility for cost-effective production on flexible, lightweight substrates. Yet, scaling up of these devices presents challenges, particularly because roughness, solvents, reactions that can impair integrity subcells within configurations. Here, we introduce a metal-free transparent conductive adhesive (TCA) material, implemented via lamination approach, scalable solution facilitates separate...
Photodynamic therapy (PDT) performance is always impaired by the characteristic hypoxic tumor microenvironment (TME) of solid tumors. To surmount this intractable issue, herein, we report design an hypoxia-tolerant MOF@TiO2 (MOF, metal–organic framework) photosensitizer (PS) consisting TiO2 nanoparticles-decorated zirconium(IV)-based meso-tetra(4-carboxyphenyl) porphine (TCPP) MOF, also demonstrate its detailed radicals generation mechanism under conditions and validate superb anticancer...
The surface passivation with the heterostructure of 2D/3D stack has been widely used for boosting efficiency n-i-p perovskite solar cells (PSCs). However, disordered quantum well width distribution 2D perovskites leads to energy landscape inhomogeneity and crystalline instability, which limits further development PSCs. Here, a versatile approach, ligand-mediated passivation, was developed produce phase-pure layer homogeneous by dual-ligand codeposition. preferential adsorption...
