“…Many MOCs are constructed from aryl/ heteroaryl ligands, placing the interior cavity in the ring current shielding zone. Hence, bound guest signals are detected at lower shifts than expected (interestingly the effect is reversed for antiaromatic panels [60] ). Binding titrations allow elucidation of association constants and can be performed whether the guest is in slow exchange or fast exchange on the NMR timescale [61] and uptake titrations can determine kinetic parameters of binding.…”

The fields of metal‐organic cages (MOCs) and metal‐organic frameworks (MOFs) are both highly topical and continue to develop at a rapid pace. Despite clear synergies between the two fields, overlap is rarely observed. This article discusses the peculiarities and similarities of MOCs and MOFs in terms of synthetic strategies and approaches to system characterisation. The stability of both classes of material is compared, particularly in relation to their applications in guest storage and catalysis. Lastly, suggestions are made for opportunities for each field to learn and develop in partnership with the other.

Metallosupramolecular chemistry has attracted the interest of generations of researches due to the versatile properties and functionalities of oligonuclear coordination complexes. Quitean umber of different discrete cages were investigated, mostly consisting of only one typeo fl igand and one type of metal cation. Looking for ever more complex structures, heterobimetallic complexes became more and more attractive, as they give access to new structural motifs and functions. In the last years substantial success has been made in the design ands ynthesis of cages consisting of more than one type of metal cations, and ar apidly growingn umber of functional materials has appeared in the literature. This Minireview describes recent developments in the field of discrete heterometallic macrocyclesa nd cages focusingo nf unctional materials that have been used as host-systems or as magnetic, photo-active,r edox-active, and even catalytically active materials.

“…16 Now the (6,6)CNB is commercially available, 17 and further investigations and applications are expected including physical properties and host-guest chemistry. 18 To clarify the usefulness of CNBs as building blocks of nanocarbons, it is necessary to investigate the reactivity of CNBs. Since the extension of carbon nanotubes using seed molecules has been reported, [19][20][21] CNBs are considered to be effective building blocks (Fig.…”
