Example Embodiment
[0074] Example 1. Preparation of pyrene-4,5,9,10-tetraimine-(2,6-dimethylanilino) [L1](R 1 Is methyl, R 2 Is hydrogen)
[0075]
[0076] 3.60g (30mmol) belongs to the compound of formula III 2,6-dimethylaniline (R 1 Is methyl, R 2 Is hydrogen) and 9.08g (90mmol) triethylamine dissolved in 100ml solvent toluene and heated to 90℃, then add 3.2ml (30mmol) TiCl 4 , White smoke appears, then add 1.33g (5mmol) of the compound pyrene-4,5,9,19-tetraketone represented by formula II. The condensation reaction was carried out for 30 minutes, and the mixture was subjected to column chromatography, eluting with a mixed solvent of petroleum ether and dichloromethane as the eluent, and the eluted fraction was detected by thin layer chromatography to obtain 1.94g of a red solid with a yield of 57%.

[0078] Example 2. Preparation of pyrene-4,5,9,10-tetraimine-(2,6-diethylanilino) [L2](R 1 Is ethyl, R 2 Is hydrogen)
[0079]
[0080] 4.47g (30mmol) 2,6-dimethylaniline and 9.08g (90mmol) triethylamine were dissolved in 100ml toluene and heated to 90℃, then 3.2ml TiCl was added 4 , White smoke appears, then add 1.33g (5mmol) of pyrene-4,5,9,19-tetraketone. The condensation reaction was carried out for 30 minutes, and the mixture was subjected to column chromatography, eluted with a mixed solvent of petroleum ether and ethyl acetate as the eluent, and the eluted fraction was detected by thin layer chromatography to obtain 0.86 g of a red solid with a yield of 32.0%.
[0081] The structure confirmation data is as follows: 1 H NMR(400MHz, CDCl 3 ,ppm): 8.36(d,J=8.0Hz,2H,Ph-H),7.11-7.04(m,10H,Ph-H),6.96-6.83(m,6H,Ph-H),2.52-2.46( m,4H,2×CH 2 ),2.39-2.34(m,4H,2×CH 2 ),1.69-1.62(m,8H,4×CH 2 ),0.87(t,J=7.6Hz,12H,4×CH 3 ),0.73(t,J=7.6Hz,12H,4×CH 3 ). 13 C NMR(100MHz, CDCl 3 ,ppm): 157.2, ...
