Paragraph 0040-0041; 0044, (2019/07/01)
The invention relates to a micromolecular hole transport material applied to a solution processing type organic electroluminescent device. The micromolecular hole transport material is prepared according to the following steps: adding a planar N heterocyclic ring and 4-fluoronitrobenzene into a reaction bottle according to a molar ratio of 1:1 to 1:1.5 with DMF as a solvent and K2CO3 as an acid binding agent, and conducting reacting at 100-120 DEG C for 5-10 hours to obtain a nitro compound; and reducing the obtained nitro compound by using SnCl2.H2O in a molar ratio of 1:2 to 1: 3, and carrying out a reflux reaction in ethanol for 4-6 hours. The end group of the micromolecular hole transport material is a planar N-heterocycle. The hole transport material with an end group of a planar N heterocyclic ring and capable of being processed in a solution can be applied to the fields of organic electroluminescent devices, and also can be applied to the fields of organic solar cells, organic thin film transistors or organic photoreceptors.

A simple, rapid and efficient copper-catalyzed 1,3-dipolar cycloaddition reaction is described for the synthesis of a novel family of twelve triazolic dendrimers structurally related. The products were the result of the click reaction of three cores and four different azides in tetrahydrofuran applying a homogeneous copper catalysis. The reaction intermediates and products were obtained in very good to excellent yields using straightforward and simple work-up procedures. This new family of compounds contain electroactive moieties such as carbazole and triphenylamine which may turn them into excellent candidates for the development of optoelectronic organic materials.
