✦ Synopsis
A new approach to organic superstructure self-assembly, based on the use of pyrrole ± ester-substituted ferrocenes, is described. Specifically, di-and tetrapyrrole-substituted ferrocenes have been prepared. These species are found to form ribbon-like infinite chains in the solid state. In the case of the tetra-substituted system, self-association takes place in solution to produce small but well-defined oligomers. These oligomers were characterized in solution by VPO analysis and in the solution/gas phase by electrospray mass spectrometric methods. In the latter instance the ferrocene moiety was subjected to selective oxidation prior to analysis, a technique we term oxidative electrospray mass spectrometry (O-ESMS).
