Journal ArticleDOI
Dendrimeric Liquid Crystals: Isotropic−Nematic Pretransitional Behavior
Jian-Feng Li,Karl A. Crandall,Peihwei Chu,Virgil Percec,Rolfe G. Petschek,Charles Rosenblatt +5 more
TL;DR: In this article, the authors show that the pretransitional behavior of liquid crystalline monodendrons and dendrimers is qualitatively similar to that of low molecular weight liquid crystals, exhibiting a Landau-like divergence of the relaxation time and a logarithmic divergence of optical retardation on approaching the nematic−isotropic phase transition from above.
Journal ArticleDOI
X-ray Reflectivity Study of Langmuir Films of Amphiphilic Monodendrons
TL;DR: This paper used X-ray reflectivity and Π-area isotherms to study Langmuir films of a series of second and third-generation monodendrons with hydrophobic C12H25 alkyl tails at the periphery and hydrophilic COOHCO2CH3 or crown ether groups in the core.
Book ChapterDOI
Self-Assembly of Dendritic Dipeptides as a Model of Chiral Selection in Primitive Biological Systems
TL;DR: This approach elucidates a mechanism of selecting a homochiral relationship between dissimilar but neighboring α-amino acids through thermodynamic preference for homochirality in solution-phase and bulk supramolecular helical polymerization.
Journal ArticleDOI
Hierarchical Self-Organization of Chiral Columns from Chiral Supramolecular Spheres.
Dipankar Sahoo,Mohammad R. Imam,Mihai Peterca,Benjamin E. Partridge,Daniela A. Wilson,Xiangbing Zeng,Goran Ungar,Goran Ungar,Paul A. Heiney,Virgil Percec +9 more
TL;DR: Structural and retrostructural analysis using a combination of differential scanning calorimetry, X-ray diffraction, molecular modeling, and simulation of XRD patterns reveals that this CTTV derivative, which is functionalized with eight chiral first-generation minidendrons, self-organizes via a column-from-spheres model.
Journal ArticleDOI
Grafting of functional methacrylate polymer brushes by photoinduced SET-LRP
Mariia Vorobii,Ognen Pop-Georgievski,Andres de los Santos Pereira,Nina Yu. Kostina,Ryan L. Jezorek,Zdeňka Sedláková,Virgil Percec,Cesar Rodriguez-Emmenegger,Cesar Rodriguez-Emmenegger +8 more
TL;DR: In this paper, a photo-induced surface-initiated single electron transfer living radical polymerization (SET-LRP) is used for the grafting of polymer brushes from a wide range of methacrylate monomers.
