In the title compound, C(17)H(17)N(3)O(2)S, the five-membered ring forms dihedral angles of 53.02 (3) and 78.57 (3)° with the 3-meth-oxy-substituted and 2-meth-oxy-substituted benzene rings, respectively. In the crystal structure, mol-ecules are linked into centrosymmetric dimers via inter-molecular N-H⋯S hydrogen bonds.

The non-coplanar substituted phenyl rings at the 9-position of a fluorenyl unit can be involved in pi-electron delocalization in which the resulting oligofluorenes exhibit a very large enhancement of two-photon absorption cross sections up to 2559 GM at 710 nm.

The structural basis for the extraordinary stability of a triple-stranded oligonucleotide in which the third strand contains 2'-aminoethoxy-substituted riboses is investigated by NMR spectroscopy. The enhanced stability of the modified triplex in comparison to the unmodified DNA triplex of the same sequence can be attributed to strong interactions of the aminoethoxy groups of the third strand w...

In the title compound, C(19)H(11)N(3)O(2)SClBr, the chromene ring system and the thia-zole ring are each approximately planar, with maximum deviations of 0.033 (3) Å and 0.006 (3) Å, respectively. The mol-ecule adopts an E configuration about the central C=N double bond. The central thia-zole ring makes dihedral angles of 9.06 (14)° and 12.07 (11)° with the chloro-substituted phenyl ring and th...

A series of greenhouse experiments was conducted to elucidate the postinfection development of Heterodera glycines in response to applications of alachlor and fenamiphos. The rate of H. glycines maturation on a susceptible soybean cultivar was not altered by 1.0 mug alachlor/g soil but was completely inhibited by 1.0 or 1.5 mug fenamiphos/g soil. An alachlor-fenamiphos combination allowed devel...

Additional tests of 178 cultivars and lines of soybean against soybean cyst nematode are reported. Cultivars are available with some level of resistance to races 1, 2, 3, 4, 5, 6, 9, and 14, but in some cases the resistance level is moderate. No cultivar or line (except possibly PI 437654) has resistance to all of the races tested. Thirteen cultivars and lines, however, were resistant or modera...

We present a joint molecular dynamics (MD)/kinetic Monte Carlo (KMC) study aimed at the atomistic description of charge transport in stacks of liquid-crystalline tetraalkoxy-substituted, metal-free phthalocyanines. The molecular dynamics simulations reproduce the major structural features of the mesophases, in particular, a phase transition around 340 K between the rectangular and hexagonal pha...

Effects of a mixture of the postemergence herbicides acifluorfen and bentazon, and simulated defoliation expected from green cloverworm on population densities of Heterodera glycines were determined in field plots in Iowa. The herbicide mixture and defoliation each suppressed soybean growth. Population densities of H. glycines were generally lower in herbicide-treated than untreated plots. Popu...

Chiral ligand-modified polyoxometalates (POMs) were successfully synthesized by the introduction of BINOL into the dititanium-substituted POM in an organic medium and characterized by X-ray crystallography, spectroscopy, and elemental analyses. These BINOL-modified POMs were stable in the solution state and showed catalytic activity for asymmetric oxidation of thioanisole.
