Interlocked Porphyrin Switches [PDF]
Chemistry – A European Journal, 2013 AbstractWe describe the synthesis of a series of interlocked structures from porphyrin–glycoluril cage compounds and bis(olefin)‐terminated viologens by an olefin‐metathesis protocol. The length of the chain connecting the olefin substituents with the viologen has a marked effect on the products of the ring‐closure reaction.

Advanced Functional Materials, EarlyView.Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.

The biosynthesis of porphyrins
Ergebnisse der Physiologie Biologischen Chemie und Experimentellen Pharmakologie, 1948 This article is intended as a summary of some of the work which has been done, over the past ten years, on the biosynthesis of porphyrins. The treatment accorded to this subject should not be considered to be that of an exhaustive review article. It will consider only those papers which, in the author’s opinion, are most pertinent to the particular ...

ALCOHOL AND PORPHYRIN METABOLISM [PDF]
Alcohol and Alcoholism, 1985 Alcohol is a porphyrinogenic agent which may cause disturbances in porphyrin metabolism in healthy persons as well as biochemical and clinical manifestations of acute and chronic hepatic porphyrias. After excessive consumption of alcohol, a temporary, clinically asymptomatic secondary hepatic coproporphyrinuria is observable, which can become ...

Advanced Functional Materials, EarlyView.Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.
