Ferrocene-appended porphyrins: Syntheses and properties

This review article focuses on the syntheses and potential applications of ferrocene-appended porphyrin architectures. Several strategies have been developed to date to associate ferrocenyl fragments and porphyrin rings in the same molecular architecture, depending on the targeted application: (i) connection at a meso position through a direct linkage, a conjugated or saturated spacer or using a non-covalent approach and (ii) connection at a beta-pyrrolic position. Examples of ferrocene-porphyrin analogues are also presented. (C) 2007 Elsevier B.V. All rights reserved.
