pyridinium-betaine-like molecules has been reported; one family of molecules is built with a benzimidazole core and a second one with a pyrimidine moiety. The title compounds were prepared by mixing 2-chlorobenzimidazole or 2-bromopyrimidine with the corresponding pyridines (pyridine, 4-tert-butylpyridine, 4-hydroxypyridine, potassium pyridine-4-trifluoroborate, 4-dimethylaminopyridine) in acetonitrile or DMSO at
摘要已经报道了一系列类似吡啶鎓-甜菜碱的分子。用苯并咪唑核心构建一个分子家族,并用嘧啶部分构建第二个分子家族。通过将2-氯苯并咪唑或2-溴嘧啶与相应的吡啶(吡啶,4-叔丁基)混合来制备标题化合物高温下在乙腈或DMSO中的-丁基吡啶,4-羟基吡啶,吡啶-4-三氟硼酸钾,4-二甲基氨基吡啶)。通过光谱方法表征了新化合物。还报告了UV-Vis和荧光特征。初步的光致发光结果表明,宽带发射是归因于含有苯并咪唑环的化合物的共同特征。一些光谱几乎跨整个可见光谱范围,这为设计单组分全色发射器的实际机会铺平了道路。 图形摘要
