Calix[4]pyrrole-based ion pair receptors
… efforts to develop such systems on the basis of calix[4]arenes and calix[4]pyrroles. Calix[4]pyrroles and calix[4]arene derivatives bearing crown ethers or ester groups are known to act as efficient receptors for anions and cations, respectively. Therefore, the synthetic combination or …

Metal-ligand redox interaction in the multielectron chemistry of porphyrinogen coordination compounds
Metal complexes of the macrocycle porphyrinogen (calix[4]pyrrole) are studied with an emphasis on the redox activity ("non-innocence") of the ligand (Chapter I). Porphyrinogen complexes of spherical, redox-inert metal dications exist in three oxidation states, dianionic, neutral, and dicationic, …

New hydrogen bonding motifs for anion and neutral guest complexation
… that urea ligands are more effective than amido-pyrrole based ligands for binding anions in DMSO solution. Also, isoquinoline based ligands form more stable complexes than pyridine based ligands and their extra rigidity preorganises the receptor for increased anion affinities. The heteroleptic …

Non-Covalent Interactions in Water Using Synthetic and Biological Receptors
… complexes formed between four different calix[4]pyrrole receptors and thirty different pyridine N-oxide guests provide a platform for disentangling the factors that govern aromatic interactions in water and in chloroform. The three-dimensional structures of the complexes are fixed by four …
