Light‐Responsive Mononucleotide Coacervates

Chemistry – A European Journal, EarlyView.
Light‐responsive mononucleotide coacervates undergo reversible phase transitions via azobenzene photoisomerization. Coacervates with high‐valency azobenzenes remain stable under UV light, while those with low‐valency azobenzenes dissolve, enabling nucleotide release. This minimal system highlights the potential role of light for exploring energy‐driven

Electron Transport Bilayer Design for Perovskite‐Based Tandem Solar Cells Using Thermal Evaporation

Chemistry–Methods, EarlyView.
We provide a comprehensive explanation of designing a bi‐layer electron transport layer with a fullerene layer using the evaporation method in inverted perovskite solar cells (PSCs) and perovskite‐based tandem solar cells (PTSCs). Furthermore, we provide candidate materials for a bi‐layer and suggest a fullerene/SnO2 bi‐layer configuration for high ...

The Photophysics of Nucleic Acids: Consequences for the Emergence of Life

ChemSystemsChem, Volume 5, Issue 1, January 2023., 2023
Photochemical reactions in nucleic acids induced by ultraviolet (UV) radiation could have played an important role in the prebiotic selection of the building blocks of life. This Review summarizes the quantum efficiencies of the photorelaxation pathways of nucleic acids and discusses its implications for the emergence of an initial sequence pool on ...

RNA Oligomerisation without Added Catalyst from 2′,3′‐Cyclic Nucleotides by Drying at Air‐Water Interfaces**

ChemSystemsChem, Volume 5, Issue 1, January 2023., 2023
Without catalyst! A non‐enzymatic, spontaneous route to the formation of short, mixed‐sequence RNA strands from 2′,3′‐cyclic ribonucleotides is shown. The reaction occurs by drying at the air–water interfaces. Abstract For the emergence of life, the abiotic synthesis of RNA from its monomers is a central step.

Diazonium Salts in Visible Light Photocatalysis – a Focused Overview of their Application in Continuous Flow Synthesis

ChemPhotoChem, EarlyView.
The combination of continuous flow technology and visible light photocatalysis has been used to improve the safety and productivity of reactions with diazonium salts as reactive intermediates. This approach has proven to be a reliable method for various organic synthesis routes with diazonium salts under mild and well‐defined conditions.

Water‐Soluble Pd‐Imidate Complexes as Versatile Catalysts for the Modification of Unprotected Halonucleosides

The Chemical Record, Volume 22, Issue 12, December 2022., 2022
Three generations of neutral and anionic water‐soluble palladium complexes act as versatile catalysts for the modification of unprotected halonucleosides. Abstract Modification of unprotected nucleosides has been attracting continuous interest, since these building blocks themselves and their phosphate‐upgraded corresponding nucleotides have shown a ...
