By constructing an aromatic hydrocarbon framework around an osmium ion, chemists have created a new class of organometallic compound. The in-plane metallo-annulenes are essentially carbon clusters ...

A group from Nagoya University in Japan has succeeded in performing a difficult reaction to build the bases that make polycyclic aromatic hydrocarbons (PAHs) used in organic LEDs, transistors, and ...

These hydrocarbons have even been shortlisted for the basis of the earliest forms of life on Earth. Not surprisingly, polycyclic aromatic hydrocarbons can be found in coal, oil and even food.
