“…The incorporation of organic sublattices largely expands the structural diversity of superlattices. Meanwhile, the organic‐inorganic synergic effect gives OIHSLs more versatile properties, especially those required for chemistry‐involved applications, such as electrocatalysis, [4] energy storage, [5] thermoelectrics, [3a] photocatalysis, [6] and most recently chemical sensing [7]…”

Organic–inorganic hybrid superlattices (OIHSLs) hold attractive physical and chemical properties, while the construction of single‐crystal covalent OIHSLs has not been achieved. Herein a coordination assembly strategy was proposed to create a single‐crystal covalent OIHSL PbBDT (BDT=1,4‐benzenedithiolate), where layered [PbS2] sublattice covalently connects with benzene sublattice. The covalent bonding offers better thermo‐/chemi‐stability, inter‐sublattice electron transport, and unique organic‐group‐functionalized surface, which may enable better performances in chemical applications than non‐covalent OIHSL. These features endow PbBDT with the highest sensitivity, the lowest detection limit and excellent selectivity towards NO2 at room temperature among all chemiresistive gas‐sensing materials with reported response time less than 2 min without the need of light assistance.

“…Recently, multifunctional three-dimensional (3D) architectures assembled by low-dimensional blocks, such as 0D nanoparticles 25 , 1D nanorods 26 , and 2D nanosheets 27,28 , have drawn wide attention owing to the novel properties produced by synergistic effects of building blocks. Assembling 2D nanosheets into 3D structure not only maintains the intrinsic performances of the 2D nanostructures but also synergistically avoids the accumulation of 2D nanosheets that would dramatically weakens the excellent properties of nanounits 29 .…”

It is a challenging task to seek a highly-efficient electrocatalyst for oxygen evolution reaction (OER) of water splitting. Non-noble Co-based nanomaterials are considered as earth-abundant and effective catalysts to lower overpotential and increase polarization current density of OER. In this work, we reported, for the first time, a “rapid solvent-evaporation” strategy for the synthesis of three-dimensional (3D) cobalt complex hierarchical architectures constructed by two-dimensional (2D) nanosheets. The 3D structured cobalt complexes have excellent performances in catalyzing OER with lower onset potential, overpotential, Tafel slope and better stability than commercial IrO2. Superior electrochemical performances would be beneficial from the unique 3D structure. This extremely simple method for 3D Co complex with good OER activities makes the complex be promising commercial OER catalyst to replace earth-rare and expensive IrO2.

“…Under these circumstances, a postprocessing is highly required to facilitate the electronic coupling and charge transport of NC films. Current approaches have focused on the chemical methods (replacing the long‐chain ligands with shorter ligands) and physical methods (such as high temperature heat treatment) . Even though by far, there is still a long way to go through for the efficient electronic coupling and charge transport of NC SLs.…”

High-efficient charge and energy transfer between nanocrystals (NCs) in a bottom-up assembly are hard to achieve, resulting in an obstacle in application. Instead of the ligands exchange strategies, the advantage of a continuous laser is taken with optimal wavelength and power to irradiate the film-scale NCs superlattices at solid-liquid interfaces. Owing to the Au-based NCs' surface plasmon resonance (SPR) effect, the gentle laser irradiation leads the Au NCs or Au@CdS core/shell NCs to attach each other with controlled pattern at the interfaces between solid NCs phase and liquid ethanol/ethylene glycol. A continuous wave 532 nm laser (6.68-13.37 W cm ), to control Au-based superlattices, is used to form the monolayer with uniformly reduced interparticle distance followed by welded superstructures. Considering the size effect to Au NCs' melting, when decreasing the Au NCs size to ≈5 nm, stronger welding nanostructures are obtained with diverse unprecedented shapes which cannot be achieved by normal colloidal synthesis. With the help of facile scale-up and formation at solid-liquid interfaces, and a good connection of crystalline between NCs, the obtained plasmonic superstructured films that could be facilely transferred onto different substrates exhibit broad SPR absorption in the visible and near-infrared regime, enhanced electric conductivities, and wide applications as surface enhanced Raman scattering (SERS)-active substrates.
