A supramolecular approach for the formation of fullerene–phthalocyanine dyads

Molecular Devices Based on Fullerenes and Carbon Nanotubes

“…The fast decay of the excited state of 1 ZnPc upon complexation with the fullerene Scheme 9.7 ammonium cation suggested the intramolecular electron transfer from 1 ZnPc as the predominant quenching mechanism. 44 Catenanes and rotaxanes represent examples of interlocked architectures. A catenane consists of two interlocked rings (it is called in this case a [2]catenane), Scheme 9.8 Scheme 9.9 9.2 FULLERENES while a rotaxane differs from a pseudorotaxane for the two bulky stoppers located at the end of the wire that prevent dethreading.…”

Synthesis of Fullerene‐Stoppered Rotaxanes Bearing Ferrocene Groups on the Macrocycle

“…In these supramolecular systems a fullerene electron-acceptor supported in one submolecular fragment is coupled with an electron-donor supported in the second component (porphyrin, [17][18][19][20][21][22][23] phthalocyanine, [24,25] ferrocene, [26][27][28] extended tetrathiafulvalene [29] and aromatic amines [30] ). Upon photoexcitation, long-lived radical pairs have been observed.…”

Modern Synthetic Approaches to Phthalonitriles with Special Emphasis on Transition-Metal Catalyzed Cyanation Reactions

“…Notably, no chromatography was required to isolate pure tetranitrile, since impurities (mostly, dppf) could be extracted from 4b by hot methanol. Tetranitrile 4b can be used to prepare dimeric phthalocyanines, which can be used as precursors to assemblies with rotaxane topology, [51,52] as well as ionophoric polymers. Figure 14.…”
