Kombinierte lösungs‐ und oberflächengestützte Synthese eines vollständig kondensierten, kreuzförmigen Phthalocyanin‐Pentamers

Angewandte Chemie, EarlyView.
Ein Phthalocyanin‐(Pc)‐Pentamer wurde durch die Kombination lösung‐ und oberflächengestützter Synthese unter Ultrahochvakuumbedingungen erhalten. Die entstandene Pc‐basierte Nanostruktur weist ein exaktes stöchiometrisches Verhältnis von 4:1 zweier unterschiedlicher Metallionen auf, mit präziser Positionskontrolle.

Combined In‐Solution and On‐Surface Synthesis of a Fully Fused Cross‐Shaped Phthalocyanine Pentamer

Angewandte Chemie International Edition, EarlyView.
A phthalocyanine (Pc) pentamer was obtained through the combination of in‐solution and on‐surface synthesis under ultra‐high vacuum conditions. The resulting Pc‐based nanostructure presents an exact 4:1 ratio of two different metal ions with precise positional control.

UHV - Kupferfallen

, 1961
Einleitung: Im Jahre 1953 gab Alpert eine Kupferfolienfalle für Öldiffusionspumpsysteme an, mit der es möglich ist, das Endvakuum für eineige Wochen unter 10-9 Torr zu halten. Nach dieser stay-down-Zeit steigt der Druck ziemlich schnell auf einige 10-8 Torr, den "Dampfdruck" des Treibmittels, an.

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

Chemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...
