High‐Pressure Synthesis of Antimony Nitride Sb3N5 and Polynitride Sb2N8 Featuring Single‐Bonded N810− Chains

open access: yesAngewandte Chemie International Edition, EarlyView.
High‐pressure reactions between Sb and molecular nitrogen in a laser‐heated diamond anvil cell led to the formation of oC32‐Sb3N5 (51(1) GPa) and mP20‐Sb2(N8), (> 100 GPa). Both phases were identified by single‐crystal x‐ray microdiffraction and are fully corroborated by density functional theory calculations.

Dibenzazepine Bridged Network Polymeric Phthalocyanines as Degradable Heterogeneous Photocatalysts

open access: yesAngewandte Chemie International Edition, EarlyView.
Dibenzazepine photodynamic bridge has been introduced to zinc and cobalt networks phthalocyanines (NP‐Pcs) to obtain degradable heterogeneous photocatalysts. For the first time, light irradiation plays a key role in “design, use and degradation” of NP‐Pcs.

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.
