In the title compound, C(35)H(30)N(4)P(2), the diphenyl-phosphanyl and diphen-yl(2-pyridyl-imino)-λ(5)-phosphanyl groups are attached to the central methyl C atom with a P-C-N angle of 114.09 (16)°. The mol-ecules stack along the b axis and inter-connect through C-H(pyrid-yl)⋯N(pyrid-yl) inter-actions, forming an infinite chain structure. The parallel chains are further inter-connected via C-H(...

ESR Signals, Spin-Trapping, N itro/N on-N itro Diphenyl Ethers, Chloroplasts, Electron Transport Phenyl-/-butylnitrone can be used to trap light-induced radicals with isolated chloroplasts, measurable by ESR technique. The radical signals are dramatically am plified and their lifetim e prolonged in the presence of peroxidizing diphenyl ethers. A pora-substitution with —N 0 2, —Cl or I is necess...

Despite being an ancient disease, tuberculosis (TB) remains the leading single-agent infectious disease killer in the world. The emerging serious problem of TB control and clinical management prompted us to synthesize a novel series of heterocyclic substituted diphenyl ether derivatives and determine their activity against the H37Rv strain of Mycobacterium. All ten compounds inhibited the growt...

The effects of the diphenyl ether herbicides HOE 29152 (methyl-2[4-(4-trifluoromethoxy) phenoxy] propanoate) and nitrofluorfen (2-chloro-1-[4-nitrophenoxy]-4-[trifluoromethyl]benzene) on photosynthetic electron transport have been examined with pea seedling and spinach chloroplasts. Linear electron transport (water to ferricyanide or methylviologen) is inhibited in treated chloroplasts, but nei...

In this study, the properties of blue organic light-emitting diodes (OLEDs), employing quantum well-like structure (QWS) that includes four different blue emissive materials of 4,4'-bis(2,2'-diphenylyinyl)-1,1'-biphenyl (DPVBi), 9,10-di(naphth-2-yl)anthracene (ADN), 2-(N,N-diphenyl-amino)-6-[4-(N,N-diphenyl amine)styryl]naphthalene (DPASN), and bis(2-methyl-8-quinolinolate)-4-(phenyl phenolato)...

Recent studies (Traub, Newhall, and Fuller, 1944, 1945; Seastone, 1947; Gump, 1945) on the compound hexachlorophene (G-11) (2,2'dihydroxy 3,5,6,3',5',6'hexachloro-diphenyl-methane)I have indicated a prolonged bacteriostatic effect on human skin. In order to explain this protracted effect, studies were conducted to determine whether hexachlorophene could be recovered from skin for several days f...
