A blue-fluorescence 2,4,6-tris(4-fluorophenyl)-1,3,5-triazine (TFPT) monomer was synthesized with high yield and high purity under mild reaction conditions. The TFPT, which had three active fluoric groups, was facilely incorporated into stable cross-linked fluorescent polymeric nanoparticles (FCPNs) via precipitation polymerization with 6-(4-hydroxyphenyl)pyridazin-3(2H)-one (HPZ). The FCPNs we...

In the crystal, C(20)H(15)N(7)O(6)S, the dihedral angle between the oxadiazole and triazine rings is 86.94 (7)°. The oxadiazole ring makes a dihedral angle of 52.96 (8)° with the phenyl ring, while the triazine ring makes a dihedral angle of 82.08 (7)° with the benzene ring. In the structure, mol-ecules are linked by a pair of N-H⋯O hydrogen bonds, forming an inversion dimer. The dimers are fur...

The herbicide triflusulfuron-methyl (systematic name: methyl 2-{[4-dimethyl-amino-6-(2,2,2-trifluoro-eth-oxy)-1,3,5-triazin-2-yl]carbamoylsulfamo-yl}-3-methyl-benzoate) and its degradation product triazine amine [systematic name: 2-amino-4-dimethyl-amino-6-(2,2,2-trifluoro-eth-oxy)-1,3,5-triazine] form a triclinic 1:1 co-crystal of the title compound, C(7)H(10)F(3)N(5)O·C(17)H(19)F(3)N(6)O(6)S,...

Morphometric, electrophoretic, and immunological procedures were used to probe the structural and physiological differences between triazine-resistant (R) and susceptible (S) isolines of canola (Brassica napus L.). The R biotype exhibited increased grana stacking and decreased amounts of starch compared to the S biotype. Likewise, characters associated with an increase in grana stacking (lower ...

In the title compound, C(7)H(9)N(5)O(2)S, the pyrazolo-[4,3-e][1,2,4]triazine fused-ring system is essentially planar [maximum deviation = 0.0420 (3) Å]. In the crystal, mol-ecules related by twofold axes are linked into a mol-ecular net via inter-molecular C-H⋯O and C-H⋯N hydrogen bonds. π-π inter-actions are observed between the triazine and pyrazole rings of mol-ecules related by the the two...

A first model of the three-dimensional structure of the photosynthetic reaction center of the mutant T1 (SerL223----Ala, ArgL217----His) from Rhodopseudomonas viridis, resistant toward the triazine herbicide terbutryn (2-methylthio-4-ethylamino-6-t-butylamino-s-triazine), has been developed from X-ray data measured to a resolution of 2.5 A. The secondary quinone, QB, which in T1 binds better th...

The asymmetric unit of the title compound, [Zn(C(4)H(8)NOS(2))(2)(C(18)H(12)N(6))]·1.5C(4)H(8)O(2), comprises a Zn-containing mol-ecule and one and a half dioxane mol-ecules as one of the solvent mol-ecules is located about a crystallographic inversion centre. The approximately square-pyramidal N(3)S(2) donor set is defined by two monodentate dithio-carbamate ligands and two pyridine and one tr...
