The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Hydrogen tetrachloroaurate(III) trihydrate( cas:16961-25-4 ) is researched.Related Products of 16961-25-4.Guo, Jiacen; Kim, Ji-Young; Zhang, Mingliang; Wang, Haonan; Stein, Aaron; Murray, Christopher B.; Kotov, Nicholas A.; Kagan, Cherie R. published the article 《Chemo- and Thermomechanically Configurable 3D Optical Metamaterials Constructed from Colloidal Nanocrystal Assemblies》 about this compound( cas:16961-25-4 ) in ACS Nano. Keywords: optical 3D metamaterials constructed colloidal nanocrystal assembly; metamaterials ultrathin lens polarizer waveplates; 3D nanofabrication; broadband circular polarizer; chiral metamaterials; circular dichroism (CD); nanocrystal assembly; nanoimprint; plasmonics. Let’s learn more about this compound (cas:16961-25-4).
Nanofabrication has limited most optical metamaterials to 2D or, often with multiple patterning steps, simple 3D meta-atoms that typically have limited built-in tunability. Here, with a one-step scalable patterning process, we exploit the chem. addressability and structural adaptability of colloidal Au nanocrystal assemblies to transform 2D nanocrystal/Ti bilayers into complex, 3D-structured meta-atoms and to thermally direct their shape morphing and alter their optical properties. By tailoring the length, number, and curvature of 3D helical structures in each meta-atom, we create large-area metamaterials with chiroptical responses of as high as ∼40% transmission difference between left-hand (LCP) and right-hand (RCP) circularly polarized light (ΔT = TRCP – TLCP) that are suitable for broadband circular polarizers and, upon thermally configuring their shape, switch the polarity of polarization rotation. These 3D optical metamaterials provide prototypes for low-cost, large-scale fabrication of optical metamaterials for ultrathin lenses, polarizers, and waveplates.
