使用新型MCS-GT @ Co(II)磁性可回收和可循环利用的催化剂,在乙醇回流条件下,开发了一种简单,高效且绿色的2,4,5-三取代和1,2,4,5-四取代的咪唑合成方法作为溶剂。通过使用戊二醛作为交联剂将壳聚糖固定在Fe 3 O 4上,然后通过乙酸钴固定Co(II)离子来制备催化剂。使用多种技术表征催化剂。对于有机产物的测定,1 H NMR,13使用13 C NMR和傅立叶变换红外光谱。还尝试了用催化剂的各个组分进行反应,但是在制备的催化剂中组分的协同作用显示出最高的产率和最短的反应时间。

The present invention relates to a novel compound for an organic photoelectric device and an organic photoelectric device including the same. The compound is represented by the following Formula 1 : [Chemical Formula 1] B- In the above Formula 1, A1 to A5, B, C, D, E, L, and n are the same as defined in the specification. The novel compound according to one embodiment of the present invention can act as a hole injection, hole transport, light emitting, or electron injection and/or transport material, and also acts as a light emitting host along with an appropriate dopant. The novel compounds are applied to an organic photoelectric device such as an organic light emitting diode, and thus provide an organic photoelectric device having a low driving voltage and improved life-span and efficiency.
