luminescent materials, three new salts containing 4-amino-1,2,4-triazole, namely, [HADO]+ A– (A = BSA (1), MBA (2) and SBA (3), ADO = 4,4′-(4-amino-4H-1,2,4-triazole-3,5-diyl) diphenol, BSA = benzene sulfonic acid, MBA = p-toluene sulfonic acid, SBA = 2-hydroxybenzoic-5-sulfonic acid), have been successfully prepared by the reaction of ADO and a set of sulfonic acids, respectively. The luminescent maximal
为了进一步开发新的发光材料,三种含有4-氨基-1,2,4-三唑的新盐,即[H ADO ] + A – ( A = BSA ( 1 )、MBA ( 2 ) 和SBA ( 3 ) , ADO = 4,4′-(4-氨基-4 H -1,2,4-三唑-3,5-二基)联苯酚, BSA = 苯磺酸, MBA = 对甲苯磺酸, SBA = 2-通过ADO反应成功制备了羟基苯甲酸-5-磺酸)和一组磺酸,分别。室温下固态的盐1 – 3的发光最大发射峰分别位于 429、434 和 461 nm 。显然,发光峰的顺序:1 < 2 < 3,可以归因于取代基的影响。与游离的ADO相比,盐1 – 3的发射最大值确实分别红移了约 27、32 和 59 nm,这表明发射带与分子间相互作用有关。化合物1 – 3通过X射线单晶衍射、FT-IR光谱和粉末X射线衍射(PXRD)对其进行了结构表征。单晶X射线衍射分析结果
