A self-assembly approach to lead selenide (PbSe) structures that have organized across multiple length scales and multiple dimensions has been achieved. These structures consist of angstrom-scale 0D PbSe crystals, synthesized via a hot solution process, which have stacked into 1D nanorods via aligned dipoles. These 1D nanorods have arranged into nanoscale 2D sheets via directional short-ranged attraction. The nanoscale 2D sheets then further aligned into larger 2D microscale planes. In this study, the authors have characterized the PbSe structures via normal and cryo-TEM and EDX showing that this multiscale multidimensional self-assembled alignment is not due to drying effects. These PbSe structures hold promise for applications in advanced materials—particularly electronic technologies, where alignment can aid in device performance.

AbstractUnderstanding and controlling self-assembly processes at multiple length scales is vital if we are to design and create advanced materials. In particular, our ability to organise matter on the nanoscale has advanced considerably, but still lags far behind our skill in manipulating individual molecules. New tools allowing controlled nanoscale assembly are sorely needed, as well as the physical understanding of how they work. Here, we report such a method for the production of highly anisotropic nanoparticles with controlled dimensions based on a morphological transformation process (MORPH, for short) driven by the formation of supramolecular bonds. We present a minimal physical model for MORPH that suggests a general mechanism which is potentially applicable to a large number of polymer/nanoparticle systems. We envision MORPH becoming a valuable tool for controlling nanoscale self-assembly, and for the production of functional nanostructures for diverse applications.

AbstractThe organization of nanostructures across several length scales by self-assembly is a key challenge in the design of advanced materials. In meeting this challenge, materials scientists can learn much from biomineralization processes in nature. These processes result in hybrid inorganic–organic materials with exquisite and optimized properties, complex forms, and hierarchical order over extended length scales.Biominerals are usually produced in the presence of an insoluble organic template as well as soluble molecules, which control inorganic crystallization, growth, and selfassembly. These processes can be mimicked successfully, resulting in inorganic–organic hybrid materials with complex form and mesoscale order via a nanoparticle selfassembly process.Various strategies can be applied, including the balancing of aggregation and crystallization, transforming and reorganizing of pre-formed nanoparticle building blocks, and face-selective coding of nanoparticle surfaces by additives for controlled self-assembly. The underlying principles of biomimetic mineralization will be described, along with selected examples showing that while much has already been achieved, the perfection of natural systems is still out of reach.
