一种1-烃基-2-取代苯基苯并咪唑类化合物合成方法及应用
摘要：
本发明提供一种1-烃基-2-取代苯基苯并咪唑类化合物有机发光材料、制备方法及应用。本发明中，首先邻苯二胺类化合物和芳香氰类化合物在磷酸和多聚磷酸催化作用下缩合反应得到一系列2-取代苯基苯并咪唑类化合物；再用1倍量的2-取代苯基苯并咪唑类化合物和1.0-1.5倍量的卤代烷烃或者卤代烯烃在1.0-6.0倍氢化钠作用下，在10-80℃反应4-24小时得到一系列1-烃基-2-取代苯基苯并咪唑类化合物。该类化合物可作为有机发光二极管的发光层或电子传输层。
摘要（英）：

The invention provides a 1-alkyl-2-substituted phenyl benzimidazole compound organic light-emitting material as well as a preparation method and application thereof. The preparation method comprises the following steps of: firstly, carrying out condensation reaction on an o-phenylenediamine compound and an aromatic cyanogens compound under the catalytic action of phosphoric acid and polyphosphoric acid to obtain a series of 2-substituted phenyl benzimidazole compounds; and reacting doubled 2-substituted phenyl benzimidazole compounds with 1.0-1.5 times of halogenated hydrocarbon or halogenated olefin under the action of 1.0-6.0 times of sodium hydride for 4-24 hours at 10-80 DEG C to obtain a series of 1-alkyl-2-substituted phenyl benzimidazole compounds. The 1-alkyl-2-substituted phenyl benzimidazole compounds can be used as a light-emitting layer or electronic transmission layer of an organic light-emitting diode.
