Polyoxometalates (POMs) can act as unique reservoirs for multiple electron transfers. As POMs display only weak absorption in the visible spectrum, they be associated with chromophores such porphyrins and porphyrin antennae. In this Minireview, research dedicated to combination of polyoxometalates is put context state art identifying challenges addressed optimization hybrid materials applicatio...

The Enterotest string test is an easy and non-invasive method for sampling duodenal fluid, which has been successfully used for the analysis of duodenal microflora, as well as biliary bile acid and lipid composition. The method was evaluated for determination of porphyrins in duodenal bile in normal subjects and subjects with porphyria, following cholecystokinin induced gall bladder contraction...

Porphyrins and the related tetrapyrrolic aacrocyclic compounds, chlorins, bacteriochlorins and corrins are prosthetic groups of a large number of biological molecules which serve diversified roles in nature. These macrocycles, coordinated to a central metal ion, perform functions such as oxygen transport and storage (hemoglobin and myoglobin), electron and energy transfer (cytochromes and chlor...

Abstract Porphyrin molecules are a widely exploited biochemical moiety, with uses in medicinal chemistry, sensing and materials science. The shape of porphyrins, as an aromatic unit, is reductively imagined to be approximately flat, regular, rigid shape, owing the popular depiction simplified skeletal model. While this regular conformation does exist, array substitution patterns synthetic porph...
