A generic view of the amphiphilic dendrimer architecture, of the effective pair potential and of the hierarchical assembly of the molecules into a cluster crystal is shown in Fig. S1. We employ the dendrimer model already introduced before in Refs. [1, 2] and based on Ref. [3]. We study amphiphilic dendrimers of second generation which have two central monomers. The dendrimers’ 14 monomers are ...

Experimental data indicates that poly(amidoamine) (PAMAM) dendrimers flatten when in contact with a substrate, i.e. they are no longer spherical, but resemble flat disks. In order to better understand the deformation behavior of these branched polymers, a series of atomistic molecular dynamics simulations is performed. The resulting flattened dendrimer conformations are compared to atomic force...

Mesoscale simulations are performed to study the complexes between a dendrimer and a vesicle of amphiphilic molecules. In particular, the assembled structures and dynamics of these complexes are investigated by tuning vesicle size and the surface tension of vesicle membrane. Our simulations demonstrate that a dendrimer-based bulge containing amphiphilic molecules forms in the vesicle membrane w...

This article is an account of the work carried out in the authors' laboratory illustrating the usefulness of dendrimer design for nanoparticle palladium catalysis. The "click" synthesis of dendrimers constructed generation by generation by 1-->3 C connectivity, introduces 1,2,3-triazolyl ligands insides the dendrimers at each generation. Complexation of the ligands by Pd(II) followed by reducti...

Multivalent conjugation of folic acid has been employed to target cells overexpressing folate receptors. Such polymer conjugates have been previously demonstrated to have high avidity to folate binding protein. However, the lack of a monovalent folic acid-polymer material has prevented a full binding analysis of these conjugates, as multivalent binding mechanisms and polymer-mass mechanisms are...

A small amount of azo-dendrimer molecules dissolved in a liquid crystal enables translational and rotational motions of microrods in a liquid crystal matrix under unpolarized UV light irradiation. This motion is initiated by a light-induced trans-to-cis conformational change of the dendrimer adsorbed at the rod surface and the associated director reorientation. The bending direction of the cis ...

The dendrimer chemistry reported offers a route to synthetic target molecules with spherical shape, well-defined surface chemistries, and dimensions that match the size of virus particles. The largest target, a generation-13 dendrimer comprising triazines linked by diamines, is stable across ranges of concentration, pH, temperature, solvent polarity and in the presence of additives. This dendri...

A first generation dendrimer comprised of a 9,9,9’,9’-tetra-n-hexyl substituted 2,2’-bifluorene core, biphenyl dendrons, and 2-ethylhexyloxy surface groups can rapidly detect high electron affinity, explosive-related analytes such as pnitrotoluene and 2,4-dinitrotoluene. Stern-Volmer analysis of the dendrimer in solution showed that the quenching could be either collisional or static but not a ...

A second or fourth generation dendrimer with primary amine as peripheral terminal groups was firstly synthesized via Michael addition and thiol-yne addition. A series of star-shaped polypeptide was synthesized by ring opening polymerization (ROP) of γ-(2-(2-methoxyethoxy)ethyl) L-glutamate (LEG2Glu) N-carboxyanhydride (NCA) using amine group terminated dendrimer as initiator. Taking advantage o...
