Designing Threefold π‐Surfaces Through Peripheral Halogenation to Shape Multidirectional Molecular Packing

open access: yesChemistry – A European Journal, EarlyView.
The complete series of hexahalogenated triptycene‐tribenzoquinones, comprising newly synthesized fluoro‐, bromo‐, and iodo‐substituted derivatives together with the previously reported chloro analogue, enables systematic comparison of their molecular properties and intermolecular interactions in relation to their crystal packing modes.

Benzylic Oxidation of Pillar[5]Arene: From Homo‐ to Cross‐Conjugated Macrocyclic Systems

open access: yesChemistry – A European Journal, EarlyView.
Selective benzylic oxidations of pillar[5]arene have been carried out to generate all the possible oxidized derivatives containing from one up to five carbonyl subunits. Effects resulting from the homo‐ and the cross‐conjugation within this series of compounds have been investigated in details and analyzed with the help of DFT calculations.

Structure‐Driven Thermal Insulation Through Single‐ and Double‐Shell Hollow Silica Nanospheres Via a Single‐Step Sacrificial‐Interlayer Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A single‐step sacrificial‐interlayer strategy enables precise modulation of inter‐shell spacing in hollow silica nanospheres, allowing direct comparison of thermal insulation characteristics between single‐ and double‐shell architectures. The hierarchical design amplifies phonon scattering and disrupts solid heat pathways, achieving an ultralow thermal
