Understanding precise structures of two-/three- dimensional covalent organic polymers through single-crystal X-ray diffraction analysis is interesting however, to grow high-quality single crystals of these materials is challenging. Here, the authors incorporate tellurium into the backbones covalent organic polymers as a concise and fast method to grow large single crystals.

Intrinsic toughening in two-dimensional transition metal dichalcogenides can be achieved simply by twisting the layers. This twisting promotes cross-layer healing and grain boundary formation, which shield fracture tips from stress concentration.

The advance in improving the operational lifetime of organic solar cells is currently limited. Here, the authors report a radical scavenger capped zinc oxide nanoparticles as the electron transport layer, achieving operationally stable devices with efficiency of 19.47%.

The metal monochalcogenides are a group of van der Waals layered semiconductors with ultra-high plasticity. It is now revealed that their plasticity is attributed to the ability to transform their stacking order or phases, coupled with the concurrent generation of a micro-crack network.

Vapour-liquid-solid process is widely used to prepare a variety of one-dimensional nanostructures, but a quantitative understanding of the growth mechanism is missing. Here, Wang et al. show that the surface curvature oscillation of the liquid tip determines the growing process and thus the morphology.

Epitaxial growth of heterostructures composed of materials with large lattice mismatch is challenging. Here, the authors reported the epitaxy of II-VI semiconductor nanorods on plasmonic noble metal, despite a lattice mismatch of more than 40%.

High-phase-purity and stable 1T′-transition metal dichalcogenide monolayers are grown on 4H-Au nanowires by a facile and rapid wet-chemical method, enabling ultrasensitive surface-enhanced Raman scattering detection.

We report the production of MoS₂ nanosheets with high phase purity, showing that the 2H-phase templates facilitate epitaxial growth of Pt nanoparticles, whereas the 1T′ phase supports single-atomically dispersed Pt atoms.

One-micrometre-thick OLEDs with low operating voltages of 5.11 V, 3.55 V and 6.88 V at 1,000 cd cm^–2 for red, green and blue devices, respectively, and long lifetimes (55,000 h, 18,000 h and 1,600 h, respectively) are realized.

A chemical-vapour-deposition-based approach enables the phase-controllable synthesis of large-scale two-dimensional β-, β′- and α-In₂Se₃ films.

Photosensitisers are used in cancer therapy to promote the formation of reactive oxygen species on irradiation with light. Here, the authors present a graphene quantum dot photosensitiser with a singlet oxygen quantum yield of approximately 1.3, and investigate its in vitro and in vivoapplications

This work not only presents photophysical processes of thermally activated delayed fluorescent emitters in a weak Fabry-Pérot cavity, but also establishes a connection between emitter orientation and Purcell effect.

Two-dimensional materials have well-defined atomic-scale structure, which has the potential to be tuned by processing. Here, substrate-induced straining during the growth of ReS₂ causes the formation of martensite-like domain structures.

The ligand-tailored SnO₂ QDs ETL with multi-functional terminal groups in situ refines the buried interfaces with both the perovskite and transparent electrode via enhanced interface binding and perovskite passivation.

3D Networked NiCo₂S₄ nanosheet array/carbon cloth composites are synthesized by a facile hydrothermal reaction and subsequent sulfurization process, and the rational material composition and structure design lead to their outstanding overall performance as an anode material in lithium-ion batteries.
