Silver coordination polymers with tri- and hexacyanoethyl-functionalized macrocyclic ligands.
Tri- and hexa-cyanoethyl functionalized 17- () and 42-membered () macrocyclic compounds were obtained by [1 + 1] (for ) or [2 + 2] (for ) cyclocondensation of the corresponding dialdehyde and diethylenetriamine, followed by hydrogenation by KBH4 and subsequent cyano-functionalization with acrylonitrile. They react with silver nitrate, leading to the formation of [AgL(1)](NO3) () and of the meta...
متن کاملCluster phases of decorated micellar solutions with macrocyclic ligands.
An aqueous self-assembled micellar system (sodium dodecyl sulfate, SDS, decorated with various adhesive sites, cryptand Kryptofix 222 and crown ether 18-Crown-6 molecules) has been investigated by dynamic light scattering (DLS) and small angle x-ray scattering (SAXS) to have insights into the micellar structure, the micellar interactions, and the aggregation properties of the system. DLS demons...
متن کاملKinetics and mechanism of macrocyclic complex formation
Macrocyclic ligands form highly selective and kinetically labile complexes with a wide range of cations, including alkali metal and alkaline earth cations. Formation rate constants are high and remarkably insensitive to ligand structure, but decrease systematically with increasing charge density of the cation this behaviour is qualitatively similar to that expected for the dissociative intercha...
متن کاملFormation of molecular ladder elements with macrocyclic platforms via linear bifunctional ligands.
Reaction between 4-aminopyridine and a dinuclear zinc(II) component of a Robson macrocyclic ligand has resulted in the formation of a molecular ladder element motif. X-ray single crystal structural analysis indicates that two pyridine rings are assembled at the same direction of the macrocycle, which are placed in a nearly parallel way via pi-pi interactions, forming a concavity structure with ...
متن کاملSupramolecular Nanofiber Formation of Macrocyclic Dendrimer
Novel macrocyclic dendrimers (Scheme 2), having two cis-1,3,5-cyclohexanetricarboxamide (1) or 1,3,5-benzenetricarboxamide units (3) in their core, were synthesized, and their self-assembly behaviors were evaluated in solution. Infrared spectroscopy of cis-1,3,5-cyclohexanetricarboxamide cored dendrimer (1) in CHCl3 indicated that formation of strong hydrogen-bonding interactions is taking plac...
