This critical review covers the timely topic of carbon nanostructures-fullerenes and carbon nanotubes-in combination with metalloporphyrins as integrative components for electron-donor-acceptor ensembles. These ensembles are typically probed in condensed media and at semi-transparent electrode surfaces. In particular, we will present a comprehensive survey of a variety of covalent (i.e., nanoco...

Olympiadane nanomolecules are a mechanically-interlocked molecule composed of five interlocking macrocycles that resembles the olympic rings. The nanomolecule is a linear pentacatenane or a catenane [1,2]. It was synthesized and named by Fraser Stoddart and co-workers in 1994 [1,2]. The molecule was designed without any practical use in mind, although other catenanes may have possible applicati...

Electrospray ionization (ESI)-mass spectrometry (MS) is generally used for the characterization of labile supramolecules in which non-covalent bonding interactions are predominant. However, molecular ions are not detected in many cases because of their instability, and even if such ions are detected, thermal decomposition generates fragment ions that also appear in the mass spectrum. Cold-spray...

Supramolecular chemistry explores the effects of non-covalent interactions on the self-organization of matter. One strand of supramolecular enquiry has led to the creation of a variety of structurally and topologically nontrivial mechanically interlocked molecules. In the pursuit of deepening the complexity of such structures we report herein the formation of a new class of mechanically interlo...

Biochemical strategies that use a combination of synthetic oligonucleotides, thermostable DNA polymerases, and DNA ligases can produce large DNA constructs up to 1 megabase in length. Although these ambitious targets are feasible biochemically, comparable technologies for the chemical synthesis of long DNA strands lag far behind. The best available chemical approach is the solid-phase phosphora...

The assembly of nanoscale capsules or cages using metal coordination represents one of the most interesting and challenging areas of chemical nanoscience. These high-symmetry capsules are invariably comprised of many metal–ligand components, which often selfassemble rapidly and in high yield into a single gigantic species—sometimes even protein-sized. However, the interest in these systems goes...
