Embodiment 1
[0087] Example 1, preparation of dibenzotetraazepine [14] annulene compound of formula VIII
[0088] Take 0.2 mol of 4-methyl-o-phenylenediamine, 0.2 mol of acetylacetone and 0.1 mol of nickel acetate tetrahydrate, put them in a 500 mL three-neck flask, add 250 mL of ethanol, protect with nitrogen gas, heat and reflux for 40 hours, the solution is dark green, and store in the refrigerator cooled to 0°C, filtered, washed twice with ethanol at 0°C, and finally washed with water, and the filter cake was dried to obtain 34.5 g of nickel annulenene complex with a yield of 80.4%.
[0089] Dissolve 0.05mol of anrocene nickel complex in 150ml of toluene, add 0.1mol of oxalyl chloride, stir, and heat properly to make the reaction appear dark red. After 15 minutes of reaction, add 0.2mol of 2,2,4,4-tetramethyl-3 - Pentanol, heated to reflux for 1 hour, the solution gradually became green and darkened, added 20ml triethylamine, continued to reflux for 1 hour, filtered after cooling, remo...
