AI Article Synopsis

  • Integrating plasticity and elasticity in anisotropic molecular crystals is challenging but can lead to complex deformations; this research reports a centimeter-long organic crystal capable of 2D elastic bending at both room and ultralow temperatures.
  • The crystal can be manually twisted to form various helical shapes, showcasing its reconfigurable properties.
  • This combination of low-temperature resistance and unique flexibility characteristics enables advanced optical transmission control and light-polarization reusability for potential applications.

Article Abstract

Integrating plasticity and elasticity in anisotropic molecular crystals is theoretically possible and is beneficial in enabling rich and complex deformations; however, it is much harder to implement in practice. Herein, we report a centimeter-long organic crystal that is two-dimensionally (2D) elastically bendable not only at room temperature but also at ultralow temperatures (-196 °C). The straight crystal can also be manually twisted and reconfigured to form arbitrary right-handed or left-handed helical structures. The integration of low-temperature-resistant (LTR) 2D elastic-bending and reconfigurable plastic-twisting deformations into one organic crystal expands the perspectives of the emerging crystal flexibility. Taking advantage of the unique multiple flexibility characteristics, spatial controllability of optical transmission for cryogenic applications and reusability of light-polarization rotations have been implemented simultaneously in an organic crystal.

Crystal symmetry, which governs the local atomic coordination and bonding environment, is one of the paramount constituents that intrinsically dictate materials' functionalities. However, engineering crystal symmetry is not straightforward due to the isotropically strong covalent/ionic bonds in crystals. Layered two-dimensional materials offer an ideal platform for crystal engineering because of the ease of interlayer symmetry operations.

Nanoporous metals have unique potentials for energy applications with a high surface area despite the percolating structure. Yet, a highly corrosive environment is required for the synthesis of porous metals with conventional dealloying methods, limiting the large-scale fabrication of porous structures for reactive metals. In this study, we synthesize a highly reactive Mg nanoporous system through a facile organic solution-based approach without any harsh etching.

Bisphenol A degradation by manganese oxides at circumneutral pH: Quantitative evaluation of dissolved Mn(III) species with pyrophosphate.

Although trivalent manganese (Mn(III)) species have been recognized as crucial intermediates in the degradation of organic contaminants by Mn oxides, quantitative research on their specific roles remains scarce. Our study investigated the degradation processes of an organic pollutant, Bisphenol A (BPA), by dissolved Mn(III) and Mn(III)-bearing oxides, and elucidated the differences of the underlying mechanisms and reaction pathways between several Mn oxides and dissolved Mn(III). Our results indicated that BPA degradation rates with Mn(III)-bearing oxides alone follow the order: δ-MnO ≫ γ-MnOOH > MnO.

Structure-Based Design of "Head-to-Tail" Macrocyclic PROTACs.

JACS Au

December 2024

State Key Laboratory of Chemical Biology, Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, No. 345 Lingling Road, Shanghai 200032, China.

Macrocyclization is a compelling strategy for conventional drug design for improving biological activity, target specificity, and metabolic stability, but it was rarely applied to the design of PROTACs possibly due to the mechanism and structural complexity. Herein, we report the rational design of the first series of "Head-to-Tail" macrocyclic PROTACs. The resulting molecule exhibited pronounced Brd4 protein degradation with low nM DC values while almost totally dismissing the "hook effect", which is a general character and common concern of a PROTAC, in multiple cancer cell lines.

Electron microscopy in its various forms is one of the most powerful imaging and structural elucidation methods in nanotechnology where sample information is generally limited by random chemical and structural damage. Here we show how a well-selected chemical probe can be used to transform indiscriminate chemical damage into clean chemical processes that can be used to characterize some aspects of the interactions between high-energy electron beams and soft organic matter. Crystals of a Dewar benzene exposed to a 300 keV electron beam facilitate a clean valence-bond isomerization radical-cation chain reaction where the number of chemical events per incident electron is amplified by a factor of up to ca.
