specific Embodiment approach 2
[0064] Specific embodiment two: the synthetic method of phosphine red / orange photothermal excitation delayed fluorescent material described in specific embodiment one, the synthetic method is as follows:
[0065] 1. Mix 2~5mmol of carbazole or 3,6-di-tert-butylcarbazole, 1mmol of 3-bromo-4-fluorobenzaldehyde, 5~20ml of dimethyl sulfoxide and 2~5mmol of potassium carbonate , stirred and reacted at 150°C for 12-24 hours, then poured into ice water, filtered with suction, dissolved the obtained solid in benzene, added 5-10 mmol of ethylene glycol, 0.1-1 mmol of p-toluenesulfonic acid, and refluxed for 3- After cooling for 12 hours, extract with water and dichloromethane, combine the organic layers, remove the organic solvent after drying, and recrystallize with absolute ethanol to obtain 9-(2-bromo-4-(1,3-dioxolane- 2-yl)phenyl)-9H-carbazole or 9-(2-bromo-4-(1,3-dioxolan-2-yl)phenyl)-3,6-di-tert-butyl-9H - carbazole;
[0066] 2. Dissolve the product synthesized in Step 1 in tet...
specific Embodiment approach 3
[0068] Specific embodiment three: the difference between this embodiment and specific embodiment two is that in step one, 3 mmol of carbazole or 3,6-di-tert-butyl carbazole, 1 mmol of 3-bromo-4-fluorobenzaldehyde, 10 ml of Dimethyl sulfoxide and 4 mmol of potassium carbonate were mixed. Others are the same as the specific implementation.
