The synthesis and crystal structural characterization of new compounds 2-6 were accomplished. As a common synthetic methodology, the Diels-Alder reaction was applied to 9,9',10,10'-tetradehydrodianthracene (TDDA) (7) to furnish the [12]annulenes 2 and 3 [16]annulene 6 and adduct 5. © 2010 Rajuri et al.

Postsynthetic modification can be used to introduce sulfonamide functionalities into MOF frameworks. Using sulfonyl chlorides as reactive intermediates, Cr-MIL-SO3H and CAU-1-NH2 have been further modified to give hitherto unknown functionalized MOFs in which a sulfonamide group is bound to the framework either by its N or its S atom. © 2014 the Partner Organisations.

We present the use of hydrazone dynamic combinatorial libraries (DCLs) to identify macrocyclic receptors that are selective for alkaline earth metal ions over alkali metal ions. In particular, the toxic heavy metal ions Sr 2+ and Ba2+ induce characteristic changes in the DCLs. Four macrocycles were isolated and characterised by LCMS, HRMS, NMR and X-ray crystallography; binding studies by UV-Vis spectroscopy confirm the selectivity observed in the DCLs.

A new [2+2] tetra-hydrazone macrocyclic receptor was significantly amplified in a dynamic combinatorial library upon templation with alkaline earth metal ions. After optimisation the product could be isolated in 95% yield and its interaction with ions was investigated by NMR and UV-Vis spectroscopy. © 2011 The Royal Society of Chemistry.

Six new lanthanide complexes of two 44-membered macrocycles have been prepared and characterised in solution. An analysis of the conformations of the free macrocycles and their lanthanide complexes both in solution (2D NMR) and in solid state (X-ray crystallography) demonstrate that the complexation induces changes in folding of the macrocycles. © The Royal Society of Chemistry 2012.
