Hydrogen peroxide (H2O2) is an indispensable industrial feedstock and energy carrier, yet its synthesis is challenging due to the energy-intensive property and complex postpurification process. Direct photocatalytic H2O2 production from water and air offers a promising approach to addressing these problems, while obtaining efficient and robust photocatalysts has been a longstanding challenge. Herein, we describe the design and synthesis of a two-dimensional conjugated BODIPY-based framework (2D CBF) via BODIPY-mediated topologic aldol-type polycondensation. The strong solar-harvesting BODIPY units and 2D extended conjugation endow the 2D CBF with near-infrared absorption and abundant oxygen adsorption sites. Consequently, the resulting 2D CBF demonstrates a remarkable H2O2 production rate up to ∼56.8 mmol h–1 gcat–1 and benchmark apparent quantum yield of 21.9% without cocatalyst and sacrificial agents, largely superior to the BODIPY molecule. In a large-scale paradigm, the 2D CBF-based floatable photocatalysis platform (∼0.2 m2) could efficiently uptake reactant (O2) from air and produce H2O2 at a rate up to ∼15 mmol h–1 m–2 under sunlight irradiation. This work highlights the two-dimensional strategy and BODIPY building blocks for designing and synthesizing highly efficient photocatalytic platforms.

Two-dimensional organic molecular crystals (2DOMCs) have emerged as promising candidates for next-generation ultrathin electronics. However, precisely and reversibly modulating their charge-transport characteristics remains a significant challenge. Herein, we report a molecular engineering strategy to create light-programmable field-effect transistors (FETs) based on a monolayer thick 2DOMCs, which is achieved by dispersing photochromic diarylethene (DAE) guests into a crystal host matrix of 2,6-bis(4-hexylphenyl) anthracene (C6-DPA). By systematically functionalizing the DAE periphery with substituents of varying electron-donating and -withdrawing strengths, we precisely tune the HOMO energy levels of the guest molecules. We identify DAE-OCH3 as the optimal dopant, which enables a 54% modulation of the FET current within just 5 s of UV light “writing” process. Notably, the optimized C6-DPA/DAE-OCH3 (15%) guest–host system exhibits approximately 85 distinct and stable current levels, corresponding to a storage capacity exceeding 6 bits, with excellent retention over 16 days. This performance represents a significant advancement in ultrathin multilevel memories based on high-mobility organic semiconductors. Our approach establishes a general platform for developing stimuli-responsive 2D organic materials with programmable (opto)electronic properties, opening new avenues for high-density data storage and future generation intelligent (opto)electronics.

Two-dimensional (2D) materials are promising candidates for solar-driven desalination. However, conventional photothermal 2D materials like transition metal carbides and nitrides (MXenes) as well as transition metal dichalcogenides (TMDs) suffer from major limitations such as their complex synthesis and low photothermal conversion efficiency. In contrast, metal phosphorus trichalcogenides (MPCh3) do not display the same drawbacks and possess widely tunable bandgaps (1.2–3.5 eV), making them ideal candidates for solar desalination. Moreover, their properties and applications related to light–matter interactions can be further enhanced by coupling with other low-dimensional nanostructures, tailoring hybrid van der Waals heterostructures of mixed dimensionality. Herein, we report the synthesis of FePS3 nanosheets/carbon nanodots (CNDs) 2D/0D nanoheterojunctions and their photothermal response when integrated into a 3D photothermal evaporator. These nanoheterojunctions exhibited high photothermal conversion performance, with an average absorbance of 90.6% from the UV to the NIR and a temperature increase of 42 °C over the blank control under 1 sun illumination for 300 s. A high water evaporation rate of 1.68 kg m–2 h–1 was observed under the same condition. Photothermal conversion and water evaporation experiments, along with femtosecond transient absorption spectroscopy (fs-TAS), photoluminescence (PL) analysis, and finite-difference time-domain (FDTD) simulations, revealed that the incorporation of CNDs and formation of the nanoheterojunction synergistically enhance localized heating and light absorption, improve trapping efficiency, and optimize nonradiative transition pathways. This study demonstrates the disruptive potential of the rational design of high-performance 2D material hybrids through MPCh3-based nanoheterojunction engineering, unveiling its transformative capability for use in solar desalination and photothermal technologies.
