Embodiment 1
[0071] Example 1: Preparation of 7-hexyl-diaza[6]helicene I (a)
[0072]
[0073] Specific steps are as follows:
[0074] (1) the organic solvent benzene is purified by atmospheric distillation, and stored under an inert atmosphere for later use;
[0075] (2) trans-9-hexyl-3-(2-quinoline-vinyl)carbazole (Ⅱa, 0.45mmol) and iodine (I 2 , 0.46mmol) join in the 500ml organic solvent benzene that step (1) purifies, stir rapidly while dissolving, after dissolving completely, logical inert gas 30 minutes;
[0076] (3) under the continuous stirring situation, 18ml propylene oxide is added in the solution of step (2) gained, make the concentration of propylene oxide in the solution be 0.51 mol / liter;
[0077] (4) irradiating the solution obtained in step (3) through quartz glass with a high-pressure mercury lamp of 500W for 10 minutes to the end of the reaction to obtain a crude product;
[0078] (5) The solvent is evaporated in vacuo, and the crude product obtained is dissolved ...
