Azobenzene cyanuric acid

By applying the principle of nucleic acid hybridization, a hydrogen-bond-mediated bilayer membrane can be designed from a pair of complementary molecular subunits 1, 2 (Figs. 4 and 5). When amphiphilic hydrogen bond pairs of alkylated chiral melamine (hydrophobic subunit 1) and quaternary ammonium - derivatized azobenzene cyanuric acid (hydrophilic subunit 2) were mixed in water, helical nanofibers (thicknesses 14-28 nm, widths 30-50 nm, pitches 180-430 nm) were immediately formed (Fig. 5, association constant 1.13 x 10 [37]. These helical nanofibers are typical of... 

Cyanuric chloride on monosubstitution with nucleophiles such as methanol or 4-amino-azobenzene followed by displacement of a second chlorine with alanine amide gave compounds which are used for precolumn derivatization of amino acids. The diastereoisomers formed are resolved by reverse-phase HPLC <92MI 6l2-0i>. Enantiomeric amino acids are separated by HPLC on bis[carbamoyl(alkyl)methylamino]-6-chloro-l,3,5-triazine derived stationary phases <93JC277>.
