Abstract
A highly efficient and selective photocatalyst, UPC‐CMP‐1 has been successfully synthesized by a Sonogashira–Hagihara coupling reaction between iron(III) 5,10,15,20‐tetrakis‐(4′‐bromophenyl) porphine and 1,4‐diethynylbenzene. The scanning electron microscopy shows UPC‐CMP‐1 possesses a dendrite‐like nanostructure. Interestingly, within 120 s, UPC‐CMP‐1 can decompose 88.3% of Congo red (CR) molecules under visible light irradiation. Furthermore, UPC‐CMP‐1 exhibits high selectivity to CR over other dyes. These results reveal that conjugated microporous polymer should be an excellent candidate on the application of dye degradation. image
