Summary: Deuteration of hydrogen-bonded phase transition crystals can increase transition temperatures, but there are rare examples showing the opposite trend due to structural changes in hydrogen bonds. In this study, an organic crystal exhibited a reversible structural phase transition and dielectric switching, with the deuterated counterpart showing a downward shift in phase transition temperature due to a geometric H/D isotope effect.

Summary: In this study, we achieved symmetry-breaking self-assembly of a defined C-1-symmetric supramolecular structure by the synergistic effects of weak binding forces. The flexible capsule framework undergoes a large structural change upon guest binding, forming a distorted resorcin[4]arene hexameric capsule with an asymmetric cavity. The location of the chiral guest in the anisotropic environment leads to modulation of its Electric Dipole (ED) and Magnetic Dipole (MD) transition moments, resulting in increased emission quantum yield and circularly polarized luminescence.

Summary: Proteins are often labeled with deuterium for structural biology techniques, and the expensive process of perdeuteration can be substituted with in-house production of deuterated carbon sources using E. coli strains adapted through laboratory evolution. This method allows for sufficient production of deuterated proteins for large volume crystal production and subsequent analysis by neutron crystallography.

Summary: This study provides new insight into tritium separation by investigating hydrogen isotope-selective exchange reaction on hydrogen-bonded fluorine sites. Fluorinated mesoporous silica, F-MCM-41_NCs, was prepared as a novel tritium sorbent that showed significantly enhanced tritium isotope separation factor compared to pristine MCM-41. The optimal separation factor of 3.3 was achieved using 0.5F-MCM-41_NC prepared with 0.5 g of NH4F per gram of MCM-41. This optimal factor is attributed to the compromise between (NH4)2SiF6 and the stability of MCM-41 framework.

Summary: A new phosphine-ligated, silver-carbonate complex catalyst has been developed for the site-selective deuteration of C-H bonds in five-membered aromatic heterocycles and active pharmaceutical ingredients. The reactions occur using CH3OD as a low-cost source of the isotope and show tolerance towards a wide range of functional groups in both polar and nonpolar solvents. Mechanistic experiments support C-H bond cleavage from a phosphine-ligated, silver-carbonate intermediate as the rate-determining step of the catalytic cycle.

Summary: Designing hydrogen-bonded organic frameworks (HOFs) with low densities and high porosities is challenging due to the preference for close packing in most molecules. Crystal structure prediction (CSP) can rank alternative crystal packings for organic molecules based on their lattice energies. By combining CSP with structure-property predictions, a previously unknown low-energy HOF (TH5-A) with remarkably low density and three-dimensional pores was discovered for triptycene trisquinoxalinedione (TH5). This TH5-A polymorph demonstrates high porosity with a surface area of 3,284 m(2) g(-1), making it one of the most porous HOFs reported.

Summary: Circular dichroism (CD) spectroscopy is a powerful technique used for distinguishing chiral enantiomers, and has been extended to solid-state samples. However, CD spectra of the same compound measured by different researchers may not be consistent due to sample preparation differences. This study explores the challenges associated with CD measurements and distinguishes between genuine and fake signals using various types of samples.

Summary: In this study, a series of hydrogen-bonded quasi-Dion-Jacobson (DJ) perovskite semiconductors, [(HOOCnH2n-2NH3)2]PbBr4 (n = 3-8), were used to establish a clearer relationship between structural distortions and optoelectronic properties. When the n ranges from 4 to 8, the compounds showed distinctive hydrogen-bonded diammonium layers containing dimerized COOH linkers and balanced photoluminescent and photodetection properties. A linear relationship between the bandgap (E(g)) and two structural parameters (D(int) and D(d)) was established, indicating the roles of interlayer distance and inorganic framework distortion. This research expands the understanding of the relationship between structures and optoelectronic properties.
