Embodiment 1
[0058] N-(3,4-dihydroxyphenethyl)-5-(1,2-dithiocyclopent-3-yl)pentanamide (TADA) (5 g, 0.0146 mol) and lipoic acid (TA) ( 3.021g, 0.0146mol) is placed in the reactor with stirring device, oil bath is heated to lipoic acid powder melting, starts to stir. Then 1,3-bis(1-methylvinyl)benzene (DIB) (4.813 g, 0.0304 mol) was added into the reactor, and heating and stirring were continued for 5 minutes. Then add ferric chloride (0.1g, 0.6165mmol) in acetone solution (50 μ l) to the reactor, the concentration of ferric chloride in acetone solution is 2g / ml, continue heating and stirring for 3 minutes, stop heating, and melt while hot The solution was sucked into a 1ml needle, cooled to room temperature, and the polymer was extruded from the pipette to obtain supramolecular polymer-1. The obtained polymer was characterized by infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM).
