Proto-porphyrin is then combined with iron to form heme.

We are exploring avenues to organize functional molecular entities into larger ensembles by using self-assembly and coordination polymers. For example, we have investigated the electron transfer behaviour through a ditopic carbene and have assembled such materials into one-dimensional polymers that can, in principal, serve as molecular wires for shuttling electrons. In an alternative approach, self-assembly in solution has been utilized to arrange complexes with a spin-labile iron center into larger aggregates, which induces cooperative spin transitions in solution. The transition temperature is predictable based on the molecular recognition units that are available for self-assembly. In a next step, we aim at transferring these aggregates onto supports, for example by using Langmuir-Blodgett techniques (collaborations with S. Brooker, Otago U; G. Morgan, UCD; T. Gunnlaugsson, TCD).
