Evidence of artefacts made of giant sloth bones in central Brazil around the last glacial maximum

The peopling of the Americas and human interaction with the Pleistocene megafauna in South America remain hotly debated. The Santa Elina rock shelter in Central Brazil shows evidence of successive human settlements from around the last glacial…

Tuning the photoluminescence properties of SLE- and MRL-active tricarbonylrhenium(I) complexes through minor structural changes of the organic ligand

Solid-state luminescence properties depend on numerous parameters, including the molecular geometry and the intermolecular interactions that take place in the solid. To clarify the role played by these parameters on the photoluminescence (PL)…

Fur glowing under ultraviolet: in situ analysis of porphyrin accumulation in the skin appendages of mammals

Examples of photoluminescence (PL) are being reported with increasing frequency in a wide range of organisms from diverse ecosystems. However, the chemical basis of this PL remains poorly defined, and our understanding of its potential ecological…

Photoinduced Electron Transfer in Clicked Ferrocene‐BODIPY‐Fullerene Conjugates

Abstract Ferrocene‐BODIPY (Fc‐BDP) conjugates in which one or two ferrocene entities are linked to the β‐positions of the BODIPY core by an ethynyl bridge have been developed. These derivatives were easily and efficiently grafted onto a dual…
