Chiroptical control in helical receptor-anion complexes.

چکیده
Dimers of appropriately arranged anion-responsive π-conjugated moieties form helical structures by interaction with chiral anions. Terphenyl-bridged dimers of dipyrrolyldiketone boron complexes show chirality induced by binding l-amino acid anions, as observed by circular dichroism (CD) and circularly polarized luminescence (CPL). The preferred configurations of helical structures depend on the geometries of the terphenyl spacer moieties.

Preparation of CuO nanoparticles by thermal decomposition of double-helical dinuclear copper(II) Schiff-base complexes
In this paper, two double helical dinuclear copper(II) complexes of bis-N,O-bidentate Schiff base ligands bis(3-methoxy-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L1) and bis(5-bromo-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L2) were prepared and characterized by elemental analyses (CHN), as well as thermal analysis. Elemental analyses (CHN) suggested that the reaction between ligands and ...
متن کاملTwo chiroptical modes of silver nanospirals.
As an emerging three-dimensional chiral metamaterial, plasmonic nanospirals (NSs) possess inherent chiroptical activity that has attracted increasing attention for developing potential photonic applications. However, the study of chiroptical activity of plasmonic NSs is still in its infancy, especially for NSs made of silver, which is a typical plasmonic material with high plasmonic quality. He...
متن کاملChiroptical switching polyguanidine synthesized by helix-sense-selective polymerization using [(R)-3,3'-dibromo-2,2'-binaphthoxy](di-tert-butoxy)titanium(IV) catalyst.
A series of chiral binaphthyl titanium alkoxide complexes were synthesized. Among them, chiral titanium complex [(R)-3,3'-dibromo-2,2'-binaphthoxy](di-tert-butoxy)titanium(IV) (R-3) exists as a crystallographic C2 dimer in the solid state but a monomer in solution at room temperature. Application of R-3 in the helix-sense-selective polymerization of achiral carbodiimide, N-(1-anthryl)-N'-octade...

متن کاملAnion-responsive covalently linked and metal-bridged oligomers.
Ethynyl-substituted acyclic anion receptors were synthesized for discrete covalently linked and metal-bridged dimers, which form various anionic complexes including double helical structures as the first examples of Cl(-)-bridged [2+2]-type complexes that are stable in the solution state.
