The kinetics of ligand exchange at a ZnII center confined in biomimetic environment is studied. metal ion bound to TMPA unit covalently capping the calix[6]arene core....

Potassium salts of p-tert-butylcalix[6]arene p-bromophenylalanine derivative formed sizable octameric cages in the solid state that were revealed by X-ray crystallographic analysis.

A pillar[6]arene-based [2]pseudorotaxane was constructed in solution and studied in the solid state, and its photo-responsive self-assembly behavior in solution was investigated.

Organometallic ruthenium(II) arene complexes containing the PTA ligand ([Ru(η(6)-arene)Cl(2)(PTA)], PTA = 1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane, termed RAPTA) show pharmacologically relevant anti-tumour properties in vitro. Two new enantiomeric pairs of RAPTA compounds, containing the chiral arene (R)- or (S)-2-phenyl-N-(1-phenylethylene)acetamide and either dichlorido or oxalato ligan...

A series of mono-cationic dinuclear have been synthesized using ((pyridi picolinamide (L2) ligands: [(h6-arene C5Me5)2M2(m-L1)Cl3]þ (M 1⁄4 Rh, 4 p-PrC6H4Me, 7; C6Me6, 8), [(h-C5Me isolated as their hexafluorophosphate IR spectroscopy. The solid state struc ray crystallographic studies. Interestin nitrogen atoms whereas the second terminal chloride ligands. Fascinatin both ruthenium centers havi...

We report the first synthesis of bridged pillararenes. Meso-form pillar[6]arenes were diastereo-selectively formed by bridging units of a per-hydroxylated pillar[6]arene in an alternating up-and-down manner with dialkyldichlorosilanes.

A pillar[5]arene dimer was synthesized by linking a mono-hydroxylated pillar[5]arene with 1,4-bis(bromomethyl)benzene. The pillar[5]arene dimer formed stronger complexes with n-alkanes than did a monomeric pillar[5]arene.
