[0101] Step S2, add 2.52g orange-red solid Rhodol and 1.00g hexamethylenetetramine to a 100mL single-mouth round-bottom flask, then add about 30mL of trifluoroacetic acid as a solvent, and stir and dissolve the above raw materials. The system is heated to 90°C, stirred and reacted at this temperature for 14h, and then 5mL of deionized water is added to the reaction system, and the reaction is continued at this temperature for 2h. After the reaction is completed, it is naturally cooled to room temperature, and the trifluoroacetic acid is rotary evaporated to dryness under vacuum, and the obtained solid is dissolved in 80mL of dichloromethane. Then, it is extracted with 80mL of saturated sodium bicarbonate aqueous solution, repeated three times, and the organic phase is collected. The crude product is separated and purified by column chromatography, and the eluent ratio is methanol: dichloromethane = 1:70. The final product is an orange solid Rhodol-CHO with a yield of about 40%.

[0102] Step S3, add 0.30g of orange solid Rhodol-CHO to a 100mL single-mouth round-bottom flask, add about 40mL of anhydrous ethanol as a solvent, and stir to dissolve. Then, add 102μL of R-(+)-ɑ-methylbenzylamine to the above solution, and heat the reaction solution to reflux for 5h.

The nuclear magnetic spectrum of the obtained circularly polarized optical switch molecule is shown as follows Figure 3 The acid-base response properties of R-Rhodol-A are shown in Figure 4 and Figure 5 ,in, Figure 4Figure A shows the changes in the circular dichroism properties of R-Rhodol-A acetonitrile solution under different acid addition conditions; Figure B shows the changes in the photoluminescence properties of R-Rhodol-A under different acid addition conditions; Figure C shows the changes in the absorbance properties of R-Rhodol-A acetonitrile solution under different acid addition conditions; Figure D shows the actual picture of the color and fluorescence changes of R-Rhodol-A acetonitrile solution under different acid addition conditions.
