| 英文摘要 | Cyclometalated platinum(ii) complex has been successfully incorporated into the (3-aminopropyl) triethoxysilane-modified channels of ordered mesoporous silica sba-15 that has large pore hexagonal channels. studies on the o-1(2) generation conclusively demonstrates that the olefins in the nano-channels of sba-15 can be enriched 8 times higher than those in the homogeneous solution as the diffusion quantum yield of singlet oxygen (o-1(2)) is assumed to be unit. the platinum( ii) complex loaded in the channel of sba-15 is stable, and the photosensitized oxidation occurs efficiently. no obvious degradation and leaching of photosensitizers is observed even after 10 runs. only a simple filtration is needed for the recycled use of the expensive noble metal catalysts. this versatile system is a good example of photochemical reactions occurring in the mesoporous silica molecular sieve. sba-15 not only provides a support for the photosensitizer, but also acts as a nano-reactor to facilitate the photooxidation. |
