AI Article Synopsis

  • The achiral compound 2,5-diphenyl-3,4-di(3-pyridyl)cyclopenta-2,4-dien-1-one reacts with zinc and mercury salts, resulting in the formation of coordination polymers.
  • These coordination polymers, [(2)ZnCl2]infinity and [(2)HgBr2]infinity, exhibit a unique property of spontaneous chiral resolution.
  • This process leads to the development of homochiral crystal colonies, where all the crystals share the same chirality.

Article Abstract

Reaction of achiral 2,5-diphenyl-3,4-di(3-pyridyl)cyclopenta-2,4-dien-1-one (2) with ZnCl2 and HgBr2, respectively, afforded the helically chiral coordination polymers [(2)ZnCl2]infinity and [(2)HgBr2]infinity, which show spontaneous chiral resolution, forming colonies of homochiral crystals.

ConspectusSymmetry is a pervasive phenomenon spanning diverse fields, from art and architecture to mathematics and science. In the scientific realms, symmetry reveals fundamental laws, while symmetry breaking─the collapse of certain symmetry─is the underlying cause of phenomena. Research on symmetry and symmetry breaking consistently provides valuable insights across disciplines, from parity violation in physics to the origin of homochirality in biology.

In two-dimensional (2D) chiral metal-halide perovskites (MHPs), chiral organic spacers induce structural chirality and chiroptical properties in the metal-halide sublattice. This structural chirality enables reversible crystalline-glass phase transitions in (-NEA)PbBr, a prototypical chiral 2D MHP where NEA represents 1-(1-naphthyl)ethylammonium. Here, we investigate two distinct spherulite states of (-NEA)PbBr, exhibiting either radial-like or stripe-like banded patterns depending on the annealing conditions of the amorphous film.

The most distinctive features of ferroelectrics are spontaneous polarization and depolarization. Ferroelectricity was first observed in Rochelle salt, a compound with a chiral component in which the molecular chirality is not affected by depolarization. For structurally chiral ferroelectrics (SCFs), such as triglycine sulfate, which lacks chiral components, the depolarization effect on chirality presents an intriguing and unexplored topic.

Background: Indoxacarb, a type of chiral pesticide, is used to control Lepidoptera insects. Most studies had focused on the environmental behavior and selective toxicity of indoxacarb enantiomers, and the mechanism behind its selective biological activity against target organisms is not well understood.

Results: Spodoptera frugiperda was selected as the target insect.

Chirality, a basic property of symmetry breaking, is crucial for fields such as biology and physics. Recent advances in the study of chiral systems have stimulated interest in the discovery of symmetry-breaking states that enable exotic phenomena such as spontaneous gyrotropic order and superconductivity. Here we examine the interaction between light chirality and electron spins in indium selenide and study the effect of magnetic field on emerging tunnelling photocurrents at the Van Hove singularity.
