Chemistry and technology of chemical fibres: Diazopyrene derivatives - promising modifiers for production of chemisorption fibre materials

The possibility of using diazopyrene derivatives containing carbonyl and oxime groups as substituents in production of sorption-active fibre filter materials for removing metal ions from wastewaters was demonstrated. A high degree of realization of the sorption properties of the fibre modified with diazopyrene derivatives in sorption of copper ions was established. © 2009 Springer Science+Business Media, Inc

Copper(II), iron(III), and chromium(III) complexes with 5,10-dioxo-4,5,9,10-tetrahydro-4,9-diazapyrene derivatives

Six copper(II), iron(III), and chromium(III) complexes with 5,10-dioxo-4,5,9,10-tetrahydro-4,9-diazapyrene derivatives (H2L 1-H2L3) have been synthesized and studied by physical methods (IR and electronic absorption spectroscopy, quantum-chemical calculations). The composition of the complexes has been determined and their stability constants in aqueous dimethylformamide solutions have been calculated. The energy characteristics, electronic structure and geometry of isolated diazapyrenes and their tautomeric forms have been calculated by the PM6 method, and their complexes have been modeled. © Pleiades Publishing, Ltd., 2010
