By the incorporation of 2,2,6,6-tetramethylpiperidineoxyl (TEMPO) radicals into 2,5-dibromobenoic acid, and further reacted with 1,3,5-triethynylbenzene through Sononashira coupling reaction, a TEMPO radical decorated conjugated microporous polymer (CMP), named CMP-3-TEMPO, was successfully synthesized. The chemical composition and structural information of CMP-3-TEMPO are characterized by SEM, XRD, FT-IR, and EPR spectra. CMP-3-TEMPO enables selective oxide a broad range of primary and secondary aromatic alcohols, and heteroatom aromatic alcohols to their corresponding aldehydes and ketones with conversion at the range of 70-100% under mild aerobic conditions (80ºC, normal atmospheres). However, the catalytic activity of CMP-3-TEMPO was significantly decreased after three catalytic cycles. The partial decomposition of CMP-3-TEMPO and the leakage of TEMPO radicals from inner might be responsible for the decreased catalytic activity.
