Crystal structures of bis[4-(dimethylamino)pyridinium] tetrakis(thiocyanato-κN)manganate(II) and tris[4-(dimethylamino)pyridinium] pentakis(thiocyanato-κN)manganate(II)

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2018
The crystal structures of the title salts, (C7H11N2)2[Mn(NCS)4] (1) and (C7H11N2)3[Mn(NCS)5] (2), consist of manganese(II) cations that are tetrahedrally (1) or trigonal–bipyramidally (2) coordinated to four or five terminal N-bonded thiocyanate ligands,

Colorimetric and Photothermal Hollow Nanocomposite Based on Silver‐Seeded Prussian Blue Analog for Dopamine Monitoring and Photothermal Sterilization

open access: yesRare Metals, EarlyView.
ABSTRACT Multi‐element Prussian blue analog (PBA) nanocomposites have attracted wide attention for their superior characteristics to single‐functional nanomaterials in extensive applications of diagnosis and therapy. In this study, a novel hollow nanocomposite was designed and fabricated by embedding S2− and Ag nanoparticles into a NiCuMnFe (PBA).

Templated synthesis of cyclic poly(ionic liquid)s

open access: yes, 2019
Charged cyclic polymers, e.g. cyclic DNAs and polypeptides, play enabling roles in organisms, but their synthesis was challenging due to the well known polyelectrolyte effect.

Substrate‐Tight Graphene Transmembrane‐nanofluidic Devices

open access: yesSmall, EarlyView.
This study demonstrates that the covalent coupling of a pyrene layer to a silicon nitride substrate using silane and peptide chemistry increases the adhesion of graphene to the substrate and prevents the delamination of graphene. 76.2% of the devices with free‐standing graphene are successful devices for ion transport measurement in 0.1 M HCl ...

Mechanofluorochromism (MFC) of Donor–π–Acceptor (D–π–A)‐Type Fluorescent Dyes

open access: yesThe Chemical Record, EarlyView.
Mechanofluorochromism (MFC) is a photophysical phenomenon that induces changes in fluorescent colors as well as colors of organic fluorescent dyes in the solid‐state by external mechanical stimuli. In this Personal Account, we offer an insight into the mechanism for the expression of MFC and present a direction in the molecular design toward creating D–

Synthesis and Characterization of a Cerium(IV) Coordination Polymer Containing Isonicotinic Acid Zwitterions

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The new coordination polymer [Ce4O2(OH)2(NO3)2(C6H5NO2)8](NO3)8 is reported. It was discovered during a ligand screening experiment. Its crystallization was studied in situ via powder X‐ray diffraction and X‐ray absorption near‐edge structure spectroscopy.

Pyrene‐Conjugated, 2‐Pyridinecarboxaldehyde Derivatives as N‐Terminus‐Specific Tags for MALDI‐ and LALDI‐MS

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Background Proteolytic processing is a fundamental post‐translational modification. Liquid chromatography–tandem mass spectrometry (LC–MS/MS) workflows are powerful for degradomic analyses but inherently sacrifice spatial information, a critical aspect for investigating biological systems such as aberrant extracellular matrix remodeling and ...

Synthesis and Characterization of Novel Pyridinium Salts of (E)-2-(Pyridin-4-ylmethylene)hydrazine-1-carboximidamide

open access: yesMolbank
We report the synthesis and characterization of the novel pyridinium salts from (E)-2-(pyridin-4-ylmethylene)hydrazine-1-carboximidamide. The pyridinium salts were obtained via the reaction of guanylhydrazone derived from pyridine-4-carbaldehyde with ...

<sup>18</sup>F-Radiopharmaceutical Diversification Enabled by Deaminative Cross-Electrophile Couplings. [PDF]

open access: yesAngew Chem Int Ed Engl
A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.

Light‐Based Molecular Tools to Precisely Monitor and Operate β‐Adrenoceptors

open access: yesMedicinal Research Reviews, Volume 46, Issue 2, Page 445-474, March 2026.
ABSTRACT β‐Adrenoceptors are important G protein–coupled receptors involved in cardiovascular, metabolic, and neurological regulation. To study their function with high precision, light‐based molecular tools have been developed offering precise spatiotemporal control.
