Part 1. the mesomorphic properties of arloxy-s-triazines and their analogs, Part 2. the synthesis and polymerization behavior of α-aminonitriles and related compounds
… synthesizing a series of three-armed aryloxy-s-triazines with aromatic Schiff's base moieties at the molecular periphery and investigate the thermal and optical behavior of these compounds. We discovered that these molecules were in fact rigid rod, or calamitic, liquid crystals based on the …

Inhibitor-Quinone Interactions in Reaction Centers From Rhodopseudomonas Sphaeroides (Herbicide, Triazine, Ubiquinone, Photosynthesis, Resistance)
… inhibitors of Q(,A)('-) oxidation, including s-triazines and benzonitriles which, in plants, are potent herbicides. These herbicides were shown to act as competitive inhibitors of Q(,B)-binding, by kinetic methods and by direct binding of ('14)C-labelled herbicide. The inhibitors were found to …

Synthesis of Novel -1, 3, 5 - Triazine - Based - Anti-Tuberculosis Drugs.
… protocols have been developed using 1,3,5-triazines due to the important biological properties which they display. The chemistry and an extensive spectrum of biological activities of s-triazines have been examined since several decades and this heterocyclic core has received emerging …

Relationships between polymer additive molecular structure and intumescent flame retardant behaviour.
… with a high nitrogen content in the form of s-triazines. The most promising was the trimethylolmelamine salt of a bis-PEPA derivative of phosphoric acid, which, on testing, proved to be more effective than the current "state of the art" intumescent additive. Metal salts of acidic …

Electron Transfer in the Reaction Center From Rhodopseudomonas Viridis (Photosynthesis, Bioenergetics, Bacteria)
… suggesting that the inhibitors (e.g. s-triazines) mimic the quinone rather than the semiquinone. The kinetics of charge recombination between the photooxidized primary donor, P('+), and the photoreduced quinone acceptors were measured. The temperature dependence of the P('+) Q(,A)('-) …

Addition of carbonyl fluoride to organic and inorganic nitriles
… aryltrifluoromethanes and 2-hydroxy-4,6-diaryl-s-triazines. Alkali metal fluorides also enhanced this reaction and suppressed the formation of 2,4,6-triaryl-s-triazine. Hith an electron withdrawing substituent on the aromatic ring, the reactions did not yield any significant quantity of the …
