Synthesis and reactions of large-ring spirodienone calixarene derivatives
The isomerism of the polyspirodienone derivatives of the large-ring p-fertbutylcalix[n]arenes (n=5,6,8) is analyzed. Monoand polyspirodienone calix[n]arene derivatives were prepared by mild oxidation of the respective calix[n]arenes and the obtained products were characterized. Reactions of the monospirodienone derivatives with hydrazines and their rearrangements to xanthenocalixarenes are desc...
متن کاملCalixarene Derivatives for the Complexation of Cesium and Thallium Cations
The synthesis and cation-binding properties of a series of Calixarene derivatives possessing alkyl chain groups, ester groups and crown ether rings have been investigated. The syntheses of Calix[4]arene crown ethers and Calix[6]arene derivatives possessing alkyl chain, ester group and crown ether ring have been described. In order to evaluate their monovalent cation binding abilities, solvent e...
متن کاملSolubility of Selected Derivatives
Pharmaceutical availability of diazepam, oxazepam and nitrazepam from solid dispersions of PEG 6000 have been studied in comparison with corresponding physical mixtures and pure benzodiazepines. Selected derivatives of 1,4-benzodiazepin-2-one are poorly water soluble drugs. The aim of this work was to report the properties of diazepamand nitrazepam-PEG 6000 solid dispersions. Differential scann...

the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
Gold nanoparticles: calixarene complexation in a mixed calixarene–alkanethiol monolayer†
This paper describes a detailed study on the complexation of pyridinium derivatives with calixarenes bound to gold nanoparticles (AuNPs). The studied calixarene derivatives are mixed with alkanethiols to formmixed monolayers on AuNP surfaces. The key findings are: (i) even a small amount (less than 11 mol%) of calixarenes can retain their complexation abilities among a majority of alkanethiols ...
