Construction of multiferrocenyl metallacycles and metallacages via coordination-driven self-assembly: from structure to functions

Abstract: Recently, the construction of discrete multiferrocenyl organometallic structures via coordination-driven self-assembly has attracted considerable attention because of their interesting electrochemical properties and wide range of applications in the areas of organometallic chemistry, electrochemistry, and materials science. Coordination-driven self-assembly has proven to be a simple yet highly efficient approach for the preparation of various multiferrocenyl metallacycles and metallacages with predetermined sh… Show more

“…Applying this methodology to 1,1′-diiodoferrocene (fc 1 I 2 ), 1,1′′′-diiodobiferrocene (fc 2 I 2 ) and 1,1′′′′′-diiodoterferrocene (fc 3 I 2 ) at high dilution, cyclo(1,1′-quinqueferrocene) (cyclo [5]; n = 5), cyclo(1,1′-sexiferrocene) (cyclo [6]; n = 6), cyclo(1,1′-septiferrocene) (cyclo [7]; n = 7) and cyclo(1,1′-noviferrocene) (cyclo [9]; n = 9) were fully or partially isolated for the first time (Fig. 1a).…”

“…Several families of organic cycles are known 2 , including cyclodextrins (n between 5 and 32), calixarenes (typically n = 4-6), cucubiturils (n = 5-8, 10) and pillararenes (n = 5-10), yet simple analogous series comprising unfunctionalized redox-active monomer units (n > 2) (for example, molecules comprising repeating metallocenes instead of repeating α-D-glucopyranosides) are practically unknown. With reference to functionalized examples, the anticipated unusual electrochemical, structural, magnetic and supramolecular properties of such materials will be related to their shape as well as the number, proximity and connectivity of their redox centres [3][4][5] . Having an internal cavity, they offer attractive opportunities as redox-active supramolecular hosts and may prove useful in molecular machinery (for example, functioning as molecular wheels) 6 .…”

“…Beyond the synthetic challenge in preparing such objects, there is a strong interest in providing them with functionality, as encountered with recently described stimuli responsive rings and cages structures [13][14][15][16]. In this context, the preparation of redox-active metalla-rings/cages which allow a redox control over their overall charge appears relevant [17,18] and we described recently the first examples of electron-rich redox-active coordination cages capable of modulating their encapsulation properties through a redox stimulus [19,20].…”
