Organic radical polymers are being developed for applications such as energy storage, catalysis and spintronics. Quantification of radical content can be nuanced, with a variety of techniques available for characterisation. This primer provides an overview and discusses the challenges of implementation to macromolecules containing pendant radicals. (Image credit: Theo A. Ellingsen.)

In this Primer Review, the topic of molecular photochromism is introduced and fundamental concepts expounded, which should enable researchers interested in the field. Additionally, a history of the development of the area is given which provides perspective on how a field develops. Moreover, key photochromic molecules and selected applications are showcased to provide the interested reader with an entry to this fascinating field of science and emerging technology.

In this short primer we will discuss the total synthesis of lysergic acid, an important precursor to lysergic acid diethylamide (LSD). Lysergic acid is also noted as a precursor for many drugs targeting the serotonin receptor family of GPCRs, including multiple known hallucinogens. We will discuss total syntheses containing B, C and D-ring cyclisations as the key step.

This Primer Review is designed to give a succinct overview of the chemistry and pharmacology of psychedelics. It is hoped that it will provide a useful resource for science undergraduates, postgraduates and their instructors, and experienced scientists who require a comprehensive and up-to-date introduction to the field.

This Primer Review is designed to give a succinct overview of the chemistry of cannabis and cannabinoids. It is hoped that it will provide a useful resource for chemistry undergraduates, postgraduates and their instructors, and experienced chemists who require a comprehensive and up to date summary of the field.
