An interesting example of a noncovalently linked organometallic superstructure (shown right) is obtained from the self‐assembly of tetrapyrrole‐substituted ferrocene. As a result of the self‐associating properties of the pyrrole–ester subunits, this system forms ribbon‐like infinite chains in the solid state and small but well‐characterized oligomers in organic solvents. Selective oxidation of the ferrocene moiety provides a cationic ferrocenium species amenable to electrospray mass spectrometric analysis.
