Two light-emitting polyphenylene dendrimers with both hole and electron transporting moieties were synthesized and characterized. Both molecules exhibited pure blue emission solely from the pyrene core and efficient surface-to-core energy transfers when characterized in a nonpolar environment. In particular, the carbazole- and oxadiazole-functionalized dendrimer (D1) manifested a pure blue emis...
BACKGROUND Immunoglobulin light chains are classified as middle molecule uremic toxins able to interact with B lymphocyte membranes leading to the activation of transmembrane signaling. The ensuing impairment of neutrophil function can contribute to the chronic inflammation state of uremic patients, and the increased risk of bacterial infections or vascular calcifications. The aim of this cross...
Different electronic effects in the starting anthracene-containing polyphenylene substrate (bottom) afford two different nanographenes under Scholl reaction conditions, namely spironanographenes (R=H) on left and a helically arranged molecular nanographene having orthogonal aromatic moieties linked by an octafluoroanthracene core (R=F) right. The stabilities of intermediate trityl cations conco...
Russian glass-filled materials based on polyphenylene sulfide were used for the first time as a structural material of parts miniature power supply devices stand-by chemical current sources. The advantages these over traditional press are shown, main which increased strength, reduced defectiveness parts, number rejects, improved technical and economic production indicators. application sulfide-...
