Synthesis of non- or antiaromatic conjugated macrocycles

Researchers at Ehime University discovered a π-stacked dimer of positively charged antiaromatic molecules stabilized upon stacking, contrary to their inherent instability. The findings suggest that intermolecular stacking can partially attenuate the intrinsic instability characteristic of antiaromatic molecules.

Scientists develop antiaromatic molecules that exhibit absorption and fluorescence bands in the near-infrared region, enabling deep biological imaging and photothermal therapy. This breakthrough holds potential for diverse NIR luminescent materials and applications in fields like healthcare, optoelectronics, and materials science.

Scientists have developed a new approach to designing materials with useful electronic and optical properties. By stacking antiaromatic units using van der Waals interactions, researchers created highly conductive liquid crystals. This breakthrough could lead to advances in organic electronics, optoelectronics, and sensing devices.

Researchers designed chiral amphiphilic pillar[5]arene derivatives to form stable chiral toroidal nanostructures and Möbius strip-like nanorings through non-covalent interactions. The assembly process exhibits solvent-dependent evolution, controlling luminescent properties and enabling the creation of functional chiral nanomaterials.

The assembly process exhibited solvent-dependent evolution, resulting in structure-dependent luminescent properties.

Researchers at NINN and SOKENDAI develop a new strategy for synthesizing three-dimensional macrocycles in a square shape, featuring acid responsiveness and recyclability. The method uses an imine bond to create the shape, respond to stimuli, and revert back.
