Thiol-ene click reaction is one of the useful organic reactions due to its high efficiency and rapidity that enable a quantitative yield without side reactions. The reaction can be proceeded by a photoredox catalysis with a dye molecule which can serve as photocatalyst. We utilize a graphitic carbon nitride (g-C3N4), a nanomaterial which effectively absorb UV and visible light to provide an electron, are used as a photocatalyst to proceed photocatalytic thiol-ene click reaction. In addition, g-C3N4 is easy to produce, and reusable, and efficient due to high quantum yield in the wavelength range of UV and visible light. We demonstrate the photocatalysis with click reaction of small molecules upon illumination by blue and UV LEDs. We further show that the photocatalysis was useful to functionalize reactive polymers by the click reaction without any other side reactions such as photocrosslinking. |
