[0058] Embodiment 1: the synthesis of organic dye I-1

[0059]

[0060] With quinoline structure diazonium salt 1a (0.6mmol), (4-methoxyphenylethynyl) trimethylsilane 2a (0.5mmol), Ph 3 PAuCl (0.05 mmol) and acetonitrile (5 mL) were mixed in a 20 mL glass test tube and sealed with a rubber stopper. The air in the test tube was removed by the freeze-thaw pump circulation method and flushed with nitrogen. After the mixture in the test tube returned to room temperature, the test tube was placed under the irradiation of a blue LED light source to react for 16 hours. After the reaction was completed, the solvent was removed, and the product was obtained as an orange solid after chromatographic separation, and the yield was 69%.
