A method, comprising:
- obtaining sidechain-modified light upconversion molecules comprising a molecular sensitizer and a molecular annihilator;
- incorporating the sidechain-modified light upconversion molecules into silica particles to form light upconversion particles;
- providing a reaction mixture comprising a photocatalyst and a photocatalytic reaction substrate;
- suspending the light upconversion particles in the reaction mixture to obtain a photocatalytic system;
- and
- exciting the photocatalyst via light upconverted by the sidechain-modified light upconversion molecules.
