Shape adjustment between multiply twinned and single-crystalline polyhedral gold nanocrystals: Decahedra, icosahedra, and truncated tetrahedra
TL;DR: Polyhedral gold nanocrystals with decahedral, icosahedral, and truncated tetrahedral shapes were synthesized by a simple one-pot polyol process in the prescence of poly(vinyl pyrrolidone) (PVP).
Journal ArticleDOI
Soluble Polyimides from Unsymmetrical Diamine with Trifluoromethyl Pendent Group
Im Sik Chung,Sang Youl Kim +1 more
TL;DR: In this article, a trifluoromethyl group unsymmetrically was inserted into the polymer chains that may reduce interactions between polyimide chains. But the results showed that polyimides are often insoluble and infusible in their fully imidized form due to their rigid chain characteristics.
Journal ArticleDOI
Soluble Polyimides Containing Benzimidazole Rings for Interlevel Dielectrics
TL;DR: In this paper, new soluble polyimides with improved adhesion to copper were synthesized from 6,4‘-diamino-2-phenylbenzimidazole (BIA) and 2,2'bis(trifluoromethyl)-4,4'diaminobiphenyl (TFDB) with 3,3'3'4'benzophenone tetracarboxylic dianhydride (BTDA) via one-pot synthetic method using N-methylpyrrolidone
Journal ArticleDOI
Soluble polyimides from unsymmetrical diamine containing benzimidazole ring and trifluoromethyl pendent group
TL;DR: In this paper, a diamine monomer containing both the benzimidazole ring and trifluoromethyl group, 6,4′-diamino-2′-trifluorsoc-yl-2-phenylbenzimidaxole, was prepared from 2-bromo-5-nitrobenzotrifluoric acid and 4nitro-1,2 -phenylenediamine, and the monomer was polymerized with ODPA, BTDA and 6FDA by using one
Journal ArticleDOI
Unprecedented Molecular Architectures by the Controlled Self‐Assembly of a β‐Peptide Foldamer
TL;DR: This presentation reports the first example of highly homogeneous, well-defined and finite architectures by the β-peptide self-assembly, presumably due to the intrinsic large conformational flexibility of natural peptides.
