Stereoselective self-assembly of atropoisomeric Pd(II) metallocycles induced by an aromatic guest.

چکیده
A new dinuclear Pd(II) metallocycle consisting of a 4,4'-bipyridin-1-ium ligand with a quinoline moiety was self-assembled in aqueous solution with the aid of template molecules; the situation found in solution in which both syn and anti or only the anti atropoisomers are observed strongly relies on the intermolecular host-guest interactions.

Stable, trinuclear Zn(II)- and Cd(II)-metallocycles: TWIM-MS, photophysical properties, and nanofiber formation.
A series of trimeric, Zn(II)- and Cd(II)-metallocycles is reported. Structural characterization of the highly stable triangles was supported by traveling-wave ion mobility-mass spectrometry (TWIM-MS) and gradient tandem mass spectrometry (gMS(2)). Their unique photophysical properties and self-assembly to form nanofibers are also described.
متن کاملEngineering Nano-aggregates: β-Cyclodextrin Facilitates the Thiol-Gold Nanoparticle Self-Assembly
The structure and morphology of nonmaterial formed by colloidal synthesis represent a subject of interest as it is a factor deciding the physicochemical properties and biological applications of nanostructures. Among various nanoparticles, gold can develop fractal assembled patterns. Herein, we report a nano-aggregate of a thiol-on-gold self-assembled structure and the influence of β-cyclodextr...

Unique three-component self-assembly of a cis-blocked 90° Pd(II) acceptor with a mixture of tri- and tetra-imidazole donors led to the self-sorting of a Pd7 molecular boat with an internal nanocavity, which catalyses the Knoevenagel condensation of a series of aromatic aldehydes with 1,3-dimethylbarbituric acid and Meldrum's acid in aqueous media.
متن کاملDetermination of mercury (II) by spectrophotometric method based on self assembly of gold nanoparticles
Due to the binding of the –COO- group with the mercury (II), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the HAc-NaAc buffer solution. The aggregation of functionalized gold nanoparticles and mercury (II)caused the shift of maximum absorption peak of the UV-Vis spectrum from 520 nm to 609 nm.Based on this principle, a simple spectropho...
متن کاملHomochiral D4-symmetric metal–organic cages from stereogenic Ru(II) metalloligands for effective enantioseparation of atropisomeric molecules
Absolute chiral environments are rare in regular polyhedral and prismatic architectures, but are achievable from self-assembly of metal-organic cages/containers (MOCs), which endow us with a promising ability to imitate natural organization systems to accomplish stereochemical recognition, catalysis and separation. Here we report a general assembly approach to homochiral MOCs with robust chemic...
