Embodiment 1
[0041] Embodiment 1: Nano self-assembly experiment of butterfly-shaped organic nanocrystals
[0042] Firstly, an aqueous solution of polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer P123 with a concentration of 1 mg / mL was prepared. Prepare a 10mL sample bottle, put it into a magnet, add 5mL of a polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer P123 aqueous solution with a concentration of 1mg / mL, and set aside.
[0043] 0.1 mg of TPA (PDAF) 3 Molecule is completely dissolved in 1mL tetrahydrofuran, under the condition of uniform rotation of the magneton, use a pipette gun to dissolve TPA(PDAF) 3The tetrahydrofuran solution of the molecule is all injected into the sample bottle containing the aqueous solution of polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer P123 within 1-2 seconds at one time, and stirred for 4-8 minutes. During this process, white flocs can be seen with the naked eye, and...
