Additionally, nucleic acid bases have been used in the dynamic assembly of mixed-metal, mixed-pyrimidine metallacalix[n]arenes [47]. In this approach, Lippert and coworkers investigated the dynamic assembly of metallacalixarenes based on platinum (Pt ), palladium (Pd°), uracil, and cytosine assemblies with mixed amines. These combinations form cyclic metallacalix[n]arenes structures with n = A and = 8. Of the metallacalix[4]arenes, compounds were formed with five, six, and eight bonded metals, and a variety of nucleobase coimecfivities (UCUC and UCCU). The dynamic nature of this assembly allows access to novel and structurally diverse set of nucleobase metallacalixarenes. [Pg.112]

Astruc has developed the concept of transition metal sandwiches acting as electron reservoir complexes. The characteristic of an electron reservoir is that the reduced form is easily generated and does not decompose to increase stability, the radical center can be sterically protected in the heart of a bulky molecular framework. The [FeCp(arene)] series of complexes, e.g. 7, are prime examples, for which variation of the arene structure modulates the redox potential. [Pg.119]

The complexes of the cis and trans ligands have the same redox potentials. c The presence of this couple was not recognized in the original paper, but it is clearly present in Fig. 6 of Ref. 71 as a small response at potentials more negative than the main response that is due to the [Os(NH3)5(T)2-(aI erce)-CH2=CHPh) ,+,2+ couple. As can be seen from its position, its redox potential is consistent with an Tj2-arene structure. d 9-Anthracenecarbonitrile. [Pg.319]
