The application discloses a preparation method and application of a hollow
conjugated microporous polymer. It belongs to the field of photocatalytic
organic synthesis and comprises the following steps: step S1, dispersing SiO2 nanosphere templates in a
triethylamine solvent; step S2, adding 4,7-dibromo-2,1,3-benzothiadiazole, dichlorobistriphenylphosphine
palladium and cuprous
iodide; step S3, slowly adding a
toluene solution of 1,3,5-triethynylbenzene; step S4, heating, stirring, washing,
etching with a
hydrofluoric acid solution, washing and
drying to obtain the hollow
conjugated microporous polymer. The hollow spherical structure of the hollow
conjugated microporous polymer enhances light capture; high specific surface area and hierarchical pores promote
mass transfer and
active site exposure; the D-A type
conjugated system constructed by BT units effectively narrows the
band gap, expands the visible
light response range and greatly improves the
charge separation efficiency; and the all-organic composition makes the hollow conjugated microporous
polymer environmentally friendly and relatively low in cost.
