英文摘要	five [bw12o40](5-)-containing metal-organic frameworks (mofs), {k[ln(h2o)(4)(pdc)](4)}[bw12o40]center dot 2h(2)o (ln=la 1 and ce 2, h(2)pdc = pyridine-2,6-dicarboxylate) and {k[ln(h2o)(3)(pdc)](4)}[bw12o40]center dot 6h(2)o (ln=tb 3, dy 4 and er 5), are synthesized hydrothermally. ln(3+) and pdc(2-) are built into 3-d mof segments containing large channels and cavities which are occupied by [bw12o40](5). herein, we report mof-containing polyoxometalates (poms) as photocatalysts to oxidize thiophene with o-2 as the oxidant. photo-excited state species ([bw12o40](5-)) are generated under uv irradiation and then h2o is oxidized into oh radicals and o-2 is reduced into o-2(2-). the active oxygen species (o-2(2-), oh) oxidize thiophene in the presence of photocatalysts and so3, co2, and h2o are obtained as photoproducts. esr measurements provide evidence that oh species are generated during photocatalysis.
