The chemical degradation of the perfluorinated sulfonic acid (PFSA) ion-exchange membrane as a result of an attack from a radical species, originating as a by-product of the oxygen reduction reaction, represents a significant limiting factor in a wid

We have synthesized the first isolable geminal bisenolates L2K2Ge[(CO)R]2 (R=2,4,6‐trimethylphenyl (2 a,b), L=THF for (2 a) or [18]‐crown‐6 for (2 b)), a new synthon for the synthesis of organometallic reagents. The formation of these derivativ

Acylgermanes are known as highly efficient photoinitiators. In this contribution, we present the synthesis of new diacylgermanes 4a–evia a multiple silyl abstraction methodology. The method outperforms the state-of-the-art approach (Corey–Seebach

We present a systematic investigation of the photophysical properties of diazocines in aqueous media. The Z-E photoconversion yields of CH2CH2- and CH2S-bridged diazocines decrease with increasing water content in acetonitrile. However, there is one

Tetraacylgermanes are known as highly efficient photoinitiators. Herein, the synthesis of mixed tetraacylgermanes 4 a–c and 6 a–e with a nonsymmetric substitution pattern is presented. Germenolates are crucial intermediates of these new synthetic

Cyclopolymerizable monomers (CPMs) are rarely described as cross-linkers, as their most prominent feature is the ability to form soluble polymer chains. In this study, we design a dimalonate-based ...

The state of health of polyfluorinated sulfonic-acid ionomer membranes (e.g. Nafion®) in low-temperature proton exchange membrane fuel cells (LT-PEMFCs) is negatively influenced by degradation phenomena occurring during their operation. As a consequ

Understanding the stability of zeolitic imidazolate framework-8 (ZIF-8) under physiological conditions is critical in biotechnology and biomedicine for biosensing, biocatalysis, and drug delivery. The use of ZIF-8 has shown that this metal organic fr

The formation of a stable triacylgermenolate 2 as a decisive intermediate was achieved by using three pathways. The first two methods involve the reaction of KOtBu or alternatively potassium with tetraacylgermane 1 yielding 2 via one electron transfe
