Studies on the synthesis and the transport properties of organic materials
A series of photo-crosslinkable arylamine-based hole-transport copolymers has been synthesized. The synthetic methodology employed allows for the redox potential of the polymer to be tuned by the incorporation of electron-donating or withdrawing moieties. Upon exposure to ultraviolet radiation, the …

Modification, curing and flame retardation of epoxy resin networks
… and fracture behavior was also studied. Arylamine functionalized poly(arylene ether sulfone)s of controlled molecular weight were synthesized as soluble, but reactive thermoplastic modifiers for aromatic amine cured epoxy resins. These materials were characterized via spectroscopy, …

Bioactivation of diacetyldapsone in cultured lung cells
… of CD-DADDS complex. The amount of arylamine produced by hydrolysis was initially monitored by the Bratton-Marshall diazotization technique. </p> <p>Only incubation with 0.01% DADDS in 1% CD showed a significant time dependent hydrolysis of DADDS over a period of 72 hours due to …

Synthesis and Characterization of Highly Porous Borazine-Linked Polymers via Dehydrogenation/Dehydrocoupling of Borane-Amine Adducts and Their Applications to Gas Storage
… by thermal dehydrogenation of several polytopic arylamine-borane adducts and has been designated Borazine-Linked Polymers (BLPs). The polymers reported are constructed of linear, triangular, and tetrahedral amine building units to form 2D and 3D frameworks. The boron sites of the pores are …

The plant-activation of m-phenylenediamine and its mutagenic, biochemical and molecular characterization
… involved in the plant-activation of an arylamine model compound, m-Phenylenediamine. This study showed that bacterial acetyl CoA:N-hydroxyarylamine O-acetyltransferase (OAT) as well as human acetyltransferase (NAT) play a key role in the bioactivation of m-PDA into potent mutagens. The …

Light-induced modulation of DNA recognition by the Rad4/XPC damage sensor protein.
… binding to two different types of DNA lesions, arylamine derivatives and, non-canonical DNA triplexes. Taken together, these studies suggest that photoactivable DNA may be used as a DNA lesion surrogate to study DNA repair mechanisms such as nucleotide excision repair and may help to provide …

Charakterisierung des allergenen Potentials von Arylaminen : in vitro Studie zur Reaktivität von T-Lymphozyten
… of different para-amino compounds and arylamines in vitro by measurement of T-cell proliferation of PBMC, T-cell lines and T-cell clones of subjects with a positive patch test result to para-Phenylenediamine. T-cell clones were generated from the blood of 14 cases and their …
