Synthesis and properties of novel Y-shaped NLO molecules containing thiazole and imidazole chromophores was written by Ren, Jun;Wang, Shi-Min;Wu, Li-Fang;Xu, Zu-Xun;Dong, Bing-Hai. And the article was included in Dyes and Pigments in 2008.Application of 6318-74-7 This article mentions the following:
Two new second-order NLO mols., derived from a five-membered heterocyclic ring (thiazole and imidazole), were synthesized. The thermal stability, optical transparency and second-order nonlinear optical (NLO) properties were investigated. As a result, good nonlinearity-transparency-thermal stability trade-off was achieved. In the experiment, the researchers used many compounds, for example, 4,5-Diphenylthiazol-2-amine (cas: 6318-74-7Application of 6318-74-7).
4,5-Diphenylthiazol-2-amine (cas: 6318-74-7) belongs to thiazole derivatives. The thiazole ring is notable as a component of the vitamin thiamine (B1). The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.Application of 6318-74-7
