We prepared two series of nanosized polymers containing s-triazine moiety by reactions of newly prepared substituted diacids chlorides derived from 2-anilino-4,6-di-(phenoxy)- and 2-(N-1-naphthylamine)-4,6-di-(phenoxy)-s-triazines with a number of com. diamines. The polymers were carefully characterized by different techniques including IR, UV, fluorescent emission, elemental and thermal analyses and SEM (SEM). The SEM images indicated that most of the polyamides were organized as well defined nano sized spheres, but in certain derivatives small amount of aggregated nanospheres was also observed Structure-property correlations based on a single or more interchange proved to be feasible. The polymers exhibited high thermal behavior and, based on the produced char yields, the limiting oxygen index (LOI) indicated that a dozen polymers were classified as “slow burning polymers” while the other dozen polymers were “self-extinguishing polymers”. Polymers derived from sym. diamine exhibited better thermal stability than those containing asym. diamines. Interestingly, while the naphthyl/phenyl interchange has no influence on the thermal properties in some cases, however, dramatic improvements were noticed in many other cases. Obviously, the pyridine/phenylene interchange has no influence on the thermal properties of the addressed polymers. The polymers exhibited emissions ranging from blue to orange wavelength depending on the nature of the signaling unit. While the introduction of a naphthyl moiety has no significant influence on the electronic properties in some cases, however, the interchange led to either appreciable red-shifted absorptions or disrupt the conjugation and thus blue-shifted absorptions in other analogs. This result enables such polymers as good candidates in different technol. applications. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine
