Routes to Cyclobutadiene and Cycloallyl Pt(II) Complexes: Dicationic Bis(Alkyne) Species as Intermediates

open access: yesChemistry – A European Journal, EarlyView.
This work demonstrates the synthesis of cationic Pt(II) η3‐cycloallyl complexes, and experimental and computational studies show a ligand bite‐angle dependence of their formation rates. The reactivity of these complexes with Brønsted acids was investigated, leading to the formation of cationic and dicationic Pt(II) η4‐cyclobutadiene complexes ...

Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport

open access: yesChemistry – A European Journal, EarlyView.
Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).

Substituent‐Dependent SERS Kinetics of Citrate‐Stabilized Gold Nanoparticles: Balancing Hotspot Formation and Colloidal Flocculation

open access: yesChemistry – A European Journal, EarlyView.
Reporter chemistry controls the operational window of liquid‐phase SERS. Para‐substituted benzenethiols induce distinct AuNPs colloidal regimes, ranging from delayed but stable hotspot formation to rapid flocculation‐dominated signal decay. The balance between SERS‐active‐state formation and colloidal loss defines whether a reporter provides reliable ...

Multimodal Fluorescent MOF@BODIPY Platform: Bridging Sensing and Mechanistic Insight

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Hybrid metal–organic frameworks (MOFs) that integrate organic chromophores constitute powerful platforms for optical sensing by combining structural order with tunable photophysics. Incorporating photoresponsive chromophores into MOFs enables sensitive probing of guest–framework interactions through well‐defined luminescent signatures. Herein,
