The invention discloses a conjugated polymer based on thiophene[3,4-c]pyrrole-4,6-dione structure, and the chemical structural formula of the conjugated polymer is shown in formula (I): The thiophene[3,4-c]pyrrole-4,6-dione structure involved in the present invention, that is, the monomer A, has the characteristics of high symmetry, planar structure, and strong electron-attracting ability. The charge is transferred to effectively adjust the energy levels of the highest occupied orbital and the lowest empty orbital of the polymer, and the absorption spectrum of the conjugated polymer based on the thiophene[3,4-c]pyrrole-4,6-dione structure is broad , Good thermal stability and suitable energy level, meeting the energy requirements of photocatalytic hydrolysis for hydrogen production. The nanoparticle has good water solubility and high thermodynamic stability, and has a hydrogen production rate of 133.9 μmol.g - 1.h- 1 at a concentration of 300 μg/mL. |
