Water Co‐Adsorption in Ultrathin Films of Ionic Liquids on Pt(111)

open access: yesChemistryOpen, EarlyView.
At 100 K, IL adsorption on D2O precovered Pt(111) partially displaces interfacial water resulting in a water‐IL co‐adsorbed layer. Upon heating to 130 K, IL ions migrate to the metal interface, thereby destabilizing adsorbed water as shown by the ≈10 K reduction in its desorption temperature.

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.

B‐N Fused Anthracene as Functional Linker for π‐Extended Viologens: Near‐IR Emission and Electrochromism

open access: yesAngewandte Chemie, Volume 138, Issue 5, 28 January 2026.
We introduce π–extended viologens with B‐N fused dipyridylanthracene (BDPA) as conduit for delocalization. Quaternization of pyridyl‐substituted BDPA by methylation or Lewis pair formation with B(C6F5)3 produces strongly colored compounds that are emissive in the near‐IR.

Synthesis of Pyridinium Moiety Containing Triazolyl Purines

open access: yesMolbank
Pyridinium salts of 2-piperidinyl-6-triazolylpurine derivatives were obtained by the introduction of pyridinium moieties into the propane-1,3-diol fragment at the N(9) position of purine to enhance the solubility of 2-amino-6-triazolylpurine derivatives ...

Deracemization of Axially Chiral Nicotinamides by Dynamic Salt Formation with Enantiopure Dibenzoyltartaric Acid (DBTA)

open access: yesMolecules, 2013
Dynamic atroposelective resolution of chiral salts derived from oily racemic nicotinamides and enantiopure dibenzoyltartaric acid (DBTA) was achieved by crystallization.

Nanozyme‐Integrated Hydrogel Targeting AGEs for Diabetic Osteoarthritis Therapy

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
A nanozyme–integrated hydrogel (PTC‐MP) exhibiting with mild photothermal effects is constructed, and a “3R” (restrain‐restore‐reinforce) strategy is proposed for diabetic osteoarthritis (DOA) treatment based on advanced glycation end products (AGEs) targeting.
