The nature of non-covalent bonding interactions was investigated through the deposition and subsequent scanning tunnelling microscopy (STM) imaging of tetra-substituted porphyrins. Porphyrins bearing iodo, bromo, nitro, pyridyl and carboxylic acid gr

A brief introduction to imidazole is given, outlining its physical and chemical properties since its discovery in 1858. The role of imidazole in the natural amino acid (S)-histidine is discussed with reference to its use in catalytic triads and histi

A series of synthetic C-3^1 alkylthioether chlorophyll derivatives, analogous to those found to occur naturally in sediment from Pup Lagoon, Antarctica, have been formed in laboratory reactions that simulate conditions that occur in many natural anox
