Chemical transformations at the macroeyclic chromophorc of expanded porphyrins are still not known. The complexation behavior of expanded porphyrins is very different from that of nonexpanded porphinoid macrocycles. The coordination hole of the expanded porphyrins is often too big for the complexation of a single metal ion, so in fact two metal ions can be chelated. With some expanded porphyrins, anion binding is observable, a striking difference to the nonexpanded porphyrins. The complexation behavior and the host-guest chemistry of expanded porphyrins is a rapidly growing field of research. The work in this field has been reviewed. Ie f...

Host-guest interactions. The area of host-guest chemistry encompasses the complexation by organic hosts of a range of both organic and inorganic guests. 

Since the seminal work of Cram on cyclophanes and resorci-narenes (1) the host-guest chemistry of container molecules has been extensively investigated and more sophisticated examples with other forms and larger cavities have been reported. Thus a large number of host-guest complexes containing neutral,...

The stoichiometric selective oxidation of the benzyhc alcohol function in (di)hydroxy-substituted benzylalcohols (Eq. 14) has been demonstrated by Nolte et al., using host-guest chemistry to steer the regiospecificity in the reaction [167-170]. The host-receptor used to construct dicopper complex 21 is based on the building block diphenylglycoluril, which was functionahzed... 

It should be stressed that there is not alwaysjustice in reseach evaluation. The selective formation of inclusion complexes by cyclodextrins (such as 11) was established by Cramer [6] at least 15 years earlier than that by crown ethers. However, cyclodextrin studies forming an independent branch of host-guest chemistry seem underestimated in spite of their considerably greater practical importance at present than that of other host macrocycles (crown ethers 17, calixarenes 18, etc.). Sometimes they are even totally neglected by discussing inclusion phenomena [7].
