“…Here we demonstrate the synthesis and assembly of colloidal particles with directional interactions that mimic those of atoms with either monovalent s or p orbitals, or multivalent sp, sp 2 , sp 3 , sp 3 d, sp 3 d 2 , or sp 3 d 3 hybridized orbitals. We do so by making particles with various numbers of patches, n=1-7 and higher, that adopt spherical, linear, triangular, tetrahedral, trigonal dipyramidal, octahedral, or pentagonal bipyramidal symmetries.…”

The ability to design and assemble 3-dimensional structures from colloidal particles is limited by the absence of specific directional bonds. As a result, complex or low-coordination structures, common in atomic and molecular systems, are rare in the colloidal domain. Here we demonstrate a general method for creating the colloidal analogues of atoms with valence: colloidal particles with chemically functionalized patches that can form highly directional bonds.These "colloidal atoms" possess all the common symmetries-and some uncommon ones-characteristic of hybridized atomic orbitals, including sp, sp 2 , sp 3 , sp 3 d, sp 3 d 2 , and sp 3 d 3 . Functionalizing the patches with DNA with single-stranded sticky ends makes the interactions between patches on different particles programmable, specific, and reversible, thus facilitating the self-assembly of particles into "colloidal molecules," including "molecules" with triangular, tetrahedral, and other bonding symmetries. Because colloidal dynamics are slow, the kinetics of molecule formation can be followed directly by optical microscopy. These new colloidal atoms should enable the assembly of a rich variety of new micro-structured materials. 2 IntroductionThe past decade has seen an explosion in the kinds of colloidal particles that can be synthesized 1,2 , with many new shapes, such as cubes 3 , clusters of spheres 4-6 and dimpled particles 7,8 reported. Because the self-assembly of these particles is largely controlled by their geometry, only a few relatively simple crystals have been made: face-centered and body-centered cubic crystals and variants 9 . Colloidal alloys increase the diversity of structures [10][11][12] , but many structures remain difficult or impossible to make. For example, the diamond lattice, predicted more than 20 years ago to have a full 3-dimensional photonic band gap 13 , still cannot be made by colloidal self-assembly because it requires 4-fold coordination. Without directional bonds, such low-coordination states are unstable.

“…It is though interesting to see how shape alone can have such an influence in how various materials self-assemble in an entropy driven process. Lately, there has been an increasing interest in the production and self-assembly of polyhedral particles [9][10][11][12][13][14][15]. Much progress has been made in enumerating and characterizing the packing of polyhedral shapes and the self-assembly of polyhedral nanocrystals into ordered superstructures [16].…”

Dedicated to my little sister.i Acknowledgments I would like to thank Marjolein Dijkstra and Anjan Gantapara for their patience and continuous help in the realization of this Thesis. I would also like to thank Djamel el Masri for sharing his knowledge of calculating the SISF.ii Abstract Self-assembly of polyhedral-shaped particles have attracted huge interest with the advent of new synthesis methods to realize these faceted particles in the lab. Recent studies have shown that polyhedral particles exhibit rich phase behavior by excluded volume interactions alone. Some of these particles are alleged to show a transition to a glass phase by quenching the liquid sufficiently fast beyond the glass transition (supercooling) such that the formation of structures with long-range order is suppressed. Despite the recent progress, no study has been made on the glass formation of polyhedral-shaped particles. Here we study the glassy behavior of polyhedral particles using advanced Monte Carlo methods. In the first part of this thesis the formation of glass by mono-disperse polyhedral particles, namely octahedra, tetrahedra and triangular cupola are discussed. At the end, the fragility of these particles is calculated and compared with that of other systems.In the second part of this thesis we performed preliminary calculations on binary mixtures of polyhedral particles. Possible candidate crystal structures are studied using the floppy box Monte Carlo method.iii

“…[41][42][43] These developments have stimulated both experimental and computational investigations of the self-assembly of cubic particles, [44][45][46] and of their phase behavior. 47,48 While the experimental cubes do not as yet have patchy surfaces, we note that, for spherical colloids, theoretical and computational work on patchy particles 49 has stimulated interesting and fruitful experimental studies on spheres with directional attraction.…”

Both biological and artificial self-assembly processes can take place by a range of different schemes, from the successive addition of identical building blocks to hierarchical sequences of intermediates, all the way to the fully addressable limit in which each component is unique. In this paper, we introduce an idealized model of cubic particles with patterned faces that allows self-assembly strategies to be compared and tested. We consider a simple octameric target, starting with the minimal requirements for successful self-assembly and comparing the benefits and limitations of more sophisticated hierarchical and addressable schemes. Simulations are performed using a hybrid dynamical Monte Carlo protocol that allows self-assembling clusters to rearrange internally while still providing Stokes-Einstein-like diffusion of aggregates of different sizes. Our simulations explicitly capture the thermodynamic, dynamic, and steric challenges typically faced by self-assembly processes, including competition between multiple partially completed structures. Self-assembly pathways are extracted from the simulation trajectories by a fully extendable scheme for identifying structural fragments, which are then assembled into history diagrams for successfully completed target structures. For the simple target, a one-component assembly scheme is most efficient and robust overall, but hierarchical and addressable strategies can have an advantage under some conditions if high yield is a priority.
