چکیده
A Directional Entropic Force Approach to Assemble Anisotropic Nanoparticles into Superlattices Report Title Not touching but sticking: By using cationic surfactant micelles as depletants, a directional entropic force approach (DEFA) assembles anisotropic nanoparticles into superlattices in solution. The micelles induce the face-to-face stacking of the nanoparticles to maximize the system's entropy. The shape of the nanoparticles determines the symmetry of the superlattice, the interparticle spacing is determined by the charged surfactant. 3

A directional entropic force approach to assemble anisotropic nanoparticles into superlattices.
Learning how to assemble inorganic nanoparticles into ordered lattices may prove to be important for applications, such as, electronics, photonics, and catalysis. Indeed, theoretical studies have shown that certain types of crystalline arrays of nanoparticles could potentially be used to generate photonic band-gap materials, negative index materials, and metamaterials at visible and infrared le...
متن کاملEntropically patchy particles: engineering valence through shape entropy.
Patchy particles are a popular paradigm for the design and synthesis of nanoparticles and colloids for self-assembly. In "traditional" patchy particles, anisotropic interactions arising from patterned coatings, functionalized molecules, DNA, and other enthalpic means create the possibility for directional binding of particles into higher-ordered structures. Although the anisotropic geometry of ...
متن کاملUnderstanding shape entropy through local dense packing.
Entropy drives the phase behavior of colloids ranging from dense suspensions of hard spheres or rods to dilute suspensions of hard spheres and depletants. Entropic ordering of anisotropic shapes into complex crystals, liquid crystals, and even quasicrystals was demonstrated recently in computer simulations and experiments. The ordering of shapes appears to arise from the emergence of directiona...
متن کاملShape allophiles improve entropic assembly.
We investigate a class of "shape allophiles" that fit together like puzzle pieces as a method to access and stabilize desired structures by controlling directional entropic forces. Squares are cut into rectangular halves, which are shaped in an allophilic manner with the goal of re-assembling the squares while self-assembling the square lattice. We examine the assembly characteristics of this s...
متن کاملPhonon-induced Anisotropic Dispersion Forces on a Metallic Substrate
Surfactant micelles (cetyltrimethylammonium chloride) adsorbed on Au(111) exhibit orientational order dictated by the gold crystal axes. To explain this phenomenon, we take into account the ionic contribution to the dielectric response of the metal. Since the motion of an ion inside the metallic lattice is restricted by its neighbors in an anisotropic way, the total dielectric response of the m...
