Macrocycles incorporating an endocyclic but non-sterically-hindering chelate: Synthesis and structural studies

Two rings of different size have been prepared both incorporating a 3,3′-biisoquinoline (biiq) chelate. The biiq ligand bears phenyl groups at its 8- and 8′-positions, which provide it with an approximate crescent shape. The incorporation of the 8,8′-diar

Pirouetting copper(I)-assembled pseudo-rotaxanes: Strong influence of the axle structure on the motion rate

Based on the gathering and threading effect of copper(I), three different pseudo-rotaxanes have been prepared and characterised in solution. They consist of the same two-chelate ring and various coordinating fragments threaded through the ring. The ring-incorporated chelates are a 2,2′,6′,6″- terpyridine (terpy) unit and a 2,9-diphenyl-1,10-phenanthroline (dpp) motif. The threaded chelates are a 2,9-bis(p-anisyl)-1,10-phenanthroline (dap), a 6,6′-bis(p-anisyl)-2,2′-bipyridine (dabipy) or a 8,8′-diphenyl-3,3′-biisoquinoline (dpbiiq) derivative. Using electrochemical techniques, the pirouetting motions of the axle within the ring through which it is threaded have been investigated. In dichloromethane/ acetonitrile, a strong dependence of the motion rate on the structure of the threaded chelate has been observed, evidencing that rigidity of the thread-contained chelate and steric hindrance lead to slow moving molecular machines. Pirouetting is the main dynamic process observed but unthreading of the string-like organic component represents another minor electrochemically induced reaction. Wiley-VCH Verlag GmbH & Co.

Sterically non-hindering endocyclic ligands of the bi-isoquinoline family

Bi-isoquinoline can be used as a building block to prepare a new family of non-sterically hindering chelates, including a macrocyclic system; the endocyclic nature of the ligands has been confirmed by the X-ray structure of an octahedral tris-chelate iron
