p-tert-Butylcalix[6]arene hexacarboxylic acid as host for Pb(II), Sr(II) and Ba(II).
p-tert-Butylcalixarene hexacarboxylic acid initially binds with low symmetry, to later adopt a highly symmetric up-down alternating conformation in the presence of Pb, Sr or Ba. The conformational dynamics for the three ions are distinct, from 15 hours, to 20 days, to 38 days, respectively.
متن کاملp-tert-Butylcalix[6]arene hexacarboxylic acid conformational switching and octahedral coordination with Pb(II) and Sr(II).
p-tert-Butylcalix[6]arene hexaacetic acid is in a symmetric cone conformation in CHCl3, but it becomes conformationally flexible in CHCl3/CH3CN (1 : 1). In this mixture the host has a strong binding affinity towards Pb(II) and instantly forms a complex of low symmetry--shortly thereafter structural reorganization occurs resulting in a high symmetry complex of Pb(II) in an octahedral cage of car...
متن کاملP-77: HOST Patterns and Sperm Quality
Background: Following the expansion of human infertility, different procedures have been utilized for separation of normal sperm during ICSI (Intra cytoplasmic sperm injection). Hypo-osmotic swelling test (HOST) is one of the tests which have been introduced for assessment of integrity of sperm membrane when confronted with hypo osmotic condition. This test may also reflect intracellular organe...
متن کاملZSM-5 Zeolite As Host Material for Semiconductor Nanoparticles
This work describes the optical and structure properties of nickel sulfide and cobalt sulfide nanoparticles in ZSM-5 zeolite. The samples were obtained by sulfidation of the Ni2+ and Co2+ ion-exchange ZSM-5 zeolites in a Na2S solution at room temperature. The optical properties of the samples were studied by UV-visible spectroscopy. Their crystalline structure and morphology were studied by X-r...
