“…Open and highly ordered structures have tailorable properties, including light weight, high porosity, low thermal conductivity, tailored stress-strain response, and photonic bandgap [159], and benefiting applications in catalyst [160], photonics [149], and metamaterials [161]. One of the promising strategies to realize such open lattice in an energy efficient way is by hierarchical assembly of patchy building blocks, which has also been exploited in polyhedral DNA scaffolds [162], collagen fibrils [163], and microscale particles [164]. The hierarchical assembly often requires two or more types of interparticle interactions that can be orthogonally triggered at different stages of assembly, which can be acquired by introducing patchiness.…”

Biological building blocks (i.e., proteins) are encoded with the information of target structure into the chemical and morphological patches, guiding their assembly into the levels of functional structures that are crucial for living organisms. Learning from nature, researchers have been attracted to the artificial analogues, “patchy particles,” which have controlled geometries of patches that serve as directional bonding sites. However, unlike the abundant studies of micron-scale patchy particles, which demonstrated complex assembly structures and unique behaviors attributed to the patches, research on patchy nanoparticles (NPs) has remained challenging. In the present chapter, we discuss the recent understandings on patchy NP design and synthesis strategies, and physical principles of their assembly behaviors, which are the main factors to program patchy NP self-assembly into target structures that cannot be achieved by conventional non-patched NPs. We further summarize the self-assembly of patchy NPs under external fields, in simulation, and in kinetically controlled assembly pathways, to show the structural richness patchy NPs bring. The patchy NP assembly is novel by their structures as well as the multicomponent features, and thus exhibits unique optical, chemical, and mechanical properties, potentially aiding applications in catalysts, photonic crystals, and metamaterials as well as fundamental nanoscience.

at Chicago. He received his M.Sc. and Ph.D. in Mechanical Engineering, both from Stanford University under the supervision of Andrew Spakowitz. For his Ph.D., he studied the impact of molecular elasticity on the behavior of semi-flexible polymers and protein self-assembly. As a postdoctoral scholar, he studied the impact of active layer morphology on bimolecular recombination losses in organic photovoltaics, and transition state theory under the supervision of Jean-Luc Bredas at Georgia Institute of Technology, and Jianshu Cao at MIT, respectively. He has published three books, more than 30 scientific papers, and served as a reviewer for major scientific journals. His current research focuses on applying molecular simulations, atomistic modeling, and density functional theory to address directed self-assembly of nanoparticles on templated surfaces, photochemistry of organic solar cells, and polymer and electrocatalyst design using machine learning and artificial intelligence.

“…In-situ liquid transmission electron microscopy (TEM) has been quickly emerging as a powerful tool to visualize the early scenarios of NC superlattice formation in real time [27,28]. Unfortunately, the low penetrating ability of the electron beam into a sample limits the study of NC assembly into only several NC monolayers, which are not only very thin but also confined to an unusual vacuum environment.…”

Nanocrystal (NC) assembly appears as one promising method towards the controllable design and fabrication of advanced materials with desired property and functionality. The achievement of a “materials-by-design” requires not only a primary structural decoding of NC assembled supercrystal at a wide range of length scales, but also an improved understanding of the interactions and changeable roles of various driving forces over the course of nucleation and growth of NC superlattice. The recent invention of a synchrotron-based X-ray supercrystallographic approach makes it feasible to uncover the structural details of NC-assembled supercrystal at unprecedented levels from atomic through nano to mesoscale. Such structural documentations can be used to trace how various driving forces interact in a competitive way and thus change relatively in strength to govern the formation of individual superlattices under certain circumstances. This short review makes use of four single supercrystals typically made up of spherical, truncate, cubic and octahedral NCs, respectively, and provides a comparable description and a reasonable analysis of the use of a synchrotron-based supercrystallographic approach to reveal various degrees of translational and orientational ordering of NCs within various superlattices. In the connection of observed structural aspects with controlled environments of NC assembly, we further address how various driving forces interact each other to develop relatively changeable roles upon variation of the NC shape to respond to the nucleation and growth of various superlattices. With the guidance of such gained insights, we provide additional examples to illustrate how realistic environments are designed into delicate control of NC assembly to achieve particular interactions between NCs towards harvesting superlattice with NC translational symmetry and atomically crystallographic orientation as desired.
