AI Article Synopsis

  • The study introduces a groundbreaking porous molecular crystal featuring rotors, which are essential for its structure.
  • The rotors, which can rotate at speeds up to 10(8) Hz at 240 K, allow the crystal to absorb gases like CO2 and I2 through its channels.
  • The dynamic behavior of the rotors can be controlled by the presence of I2, indicating potential applications for these molecular crystals in environmental sensing and managing pollutants.

Article Abstract

The first example of a porous molecular crystal containing rotors is presented. The permanently porous crystal architecture is sustained by rotor-bearing molecular rods which are connected through charge-assisted hydrogen bonds. The rotors, as fast as 10(8) Hz at 240 K, are exposed to the crystalline channels, which absorb CO2 and I2 vapors at low pressure. The rotor dynamics could be switched off and on by I2 absorption/desorption, showing remarkable change of material dynamics by the interaction with gaseous species and suggesting the use of molecular crystals in sensing and pollutant management.

Whereas single crystals of organic compounds that respond to heat or light have been reported and studied in detail, studies on crystalline organic compounds that elicit an extreme mechanical response are relatively rare in the chemical literature. A tetrafluoro(aryl)sulfanylated bicyclopentane synthesized in our laboratory was discovered to exhibit such behavior; i.e.

The locomotion of various organisms relies on the alternated elongation-contraction of their muscles or bodies. Such biomimicry can offer a promising approach to developing soft robotic devices with improved mobility and efficiency. Most strategies to mimic such motions rely on reversible size modifications of some materials upon exposure to external stimuli.

The apoptosome, a critical protein complex in apoptosis regulation, relies on intricate interactions between its components, particularly the proteins containing the Caspase Activation and Recruitment Domain (CARD). This work presents a thorough computational analysis of the stability and specificity of CARD-CARD interactions within the apoptosome. Departing from available crystal structures, we identify important residues for the interaction between the CARD domains of Apaf-1 and Caspase-9.

Bottlebrush block polymers, characterized by densely grafted side chains extending from a backbone, have recently garnered significant attention. A particularly attractive feature is the accessibility of ordered morphologies with domain spacings exceeding several hundred nanometers, a capability that is challenging to achieve with linear polymers. These large morphologies make bottlebrush block polymers promising for various applications, such as photonic crystals.
