Functionally rigid and degenerate molecular shuttles
The preparation and dynamic behavior of two functionally rigid and degenerate rotaxanes (1⋅4 PF6 and 2⋅4 PF6) in which a π-electron deficient tetracationic cyclophane, cyclobis(paraquat-p-phenylene) (CBPQT4+) ring, ...
Inclusion behavior of β-cyclodextrin with bipyridine molecules : factors governing host-guest Inclusion geometries
The 1:1 complexation of β-cyclodextrin (β-CD) with structurally similar bipyridine guests which lead to the formation of six inclusion complexes (1–6) of β-CD with 4,4′-vinylenedipyridine, 2,2′-vinylenedipyridine, ...
Rigidity-stability relationship in interlocked model complexes containing phenylene-ethynylene-based disubstituted naphthalene and benzene
Structural rigidity has been found to be advantageous for molecules if they are to find applications in functioning molecular devices. In the search for an understanding of the relationship between the rigidity and complex ...
